Battle with allies is fun. What's not that much fun however is when you already have your allies deployed at around the bottom center of the map, sluggishly blobbing together and then slowly spreading around in one direction, then blobbing up again until an enemy ship gets within sight. While not a hard blocker of deploying your own fleet, it does however prevent effectively maneuvering your own fleet to more advantageous position, not to mention is quite a hazard for more fragile Frigates if they don't really have space for maneuvering.
Alternatively, you've got Orbital Station defence. According to my experiences, allies will usually bunch up somewhere between the Station and the bottom center of the map with only a few ships daring to fly to the sides of the Station. Ships are further back if the Station in question is a Star Fortress with it's defensive drones still around, meaning, that you either cannot (or at the very least should not) deploy more fragile ships, as they get destroyed due to collission damage even before they can fire a single shot, or need to wait for quite a while to get an opening at the bottom center of the map to be able to deploy a bunch of your ships.
(Or you can deploy 2-3 at a time, but come one, where's the fun in that?)
So this begs the question: Could multiple battle entry points be added?
As far as I understand there should not be many issues with this, as standard battles already offer a number of entry (and exit) points. Standard battles offer an entry point for the player and allies at the bottom center of the battle area, and another for the enemy on the top center of the battle area (they also serve as exit points respectively).
When you are in a pursuit battle, you have 4 entry points. One point somewhere between the middle center and bottom center of the map for the retreating fleet, one point at the bottom center, where the main body of the pursuing fleet arrives from, and one point each at the right and left side of the top halves of the map for frigates to intercept.
Now, the above tells me, that it is possible to make multiple entry points for even the same main entry areas. For example, your allies would enter the map from the bottom right, while you could enter it from the bottom left. Or perhaps you (or the enemy even) could have alternative entry points for the battle if some time passes: say, you could send Frigates to attack from the sides, but unlike in pursuits, they would take some time (say, a minute of two) to get in position. Even if the latter options would not warrant any consideration, I'd still push the option to have a separate entry point for your fleet and your allies', so that they won't hog all the space in front of you.
TL;DR
Could multiple battle entry locations be implemented to prevent crowding?
