Would be highly useful in some cases, e.g. when you have one laser in each arm, one is destroyed and you don't know which one, so you can't decide if you should move your right or left arm around a building to shoot. Or just to group your weapons more easily (left arm weapons in one group, right arm weapons in another etc.).
It's no big deal to figure this out for yourself, but an indicator would be really helpful and can't be that difficult to implement. Just add "LA, LT, CT, RT, RA" etc. behind the range in the weapon list or somewhere similar.
