Actually I should be able to use Keyboard Maestro for my Mac, and create a macro that has the keystrokes needed to (once in the search results screen, or the summary screen) to select a player, change tab to recruit, select 1 call, submit it, close the player window, and then put the focus on the next player in the watch list.
I would then just hit the macro hot key once for each recruit, or bundle X nbr of macro's inside a master macro.
I'll have to wait for my next recruiting season in Knight to test this out, but it should work like that .... in theory!!
