PvP Macros (Need help)

Hi, I'm looking into macros for pvp. I'm only using 1 cahracter but was after some advice on macros for targeting.
Is there anyway to define each opponent in 2v2 using target and focus or any other method so that it is easier to swap targets and hex / windshear almost instantly? Something like a button that i press which assigns focus to one target and target to the other? Obviously i expect that i would need to click or target them first. Or if there is any other medthod where i could assgin by class or face im not sure. Any advice is appreicated.

Thanks in advance
