Heres a situation that  always gives me a little trouble:

In countering LRM's I usually end up juggling about 12 - 25 fighter squads, amongst 50 - 100 or so other craft.

Now, once battles get to a certain size, or a game to a certain length, you will usually see a little of everything in someones fleet. 

With that said, i want my 20 or so squads of fighters to go after my opponents LRM's:  using the SHIFT + attack, i use the empire tree to SHIFT + attack 3 or so stacked groups of LRM's (all done through the empire tree).  10 seconds later, i see that half of my fighters are off chasing bombers and my focus fire goes to hell.  Am I only imagining that the whole SHIFT + "action command" is not consistant in battle?!

How can someone more effectively focus the fire of their fighters when it seems that a fighters natural behavior is to be going after squads of bombers, or other fighters? Is there a way to specify the "type" (lrm/bomber) that you want your fighters to focus fire on? 

(if not, it would be a hell of an addition)

Thanks for all responses!
