profile question about switching between 2 amplifiers with 6600 and smartsdr

hi everyone... i want to be able to select between my kpa500 and my alpha99 amps. so, i thought i'd do a profile change where the kpa500 was hooked to ant1 and the alpha was on ant2. kpa500 is switched with tx1 in the band prefs and the alpha is on tx3. i'm manually switching (with a patch cable) the outputs of the amps to the antenna system. i'm not sure an antenna switch would have the isolation i need.

so i figured this is a good job for profiles! and then i learned, well... maybe not. i set up the alpha, saved a global and a tx profile. reconfigured for the kpa500 and saved another set of profiles. i expected to see the tx selections in the band setting change when i flipped from one to the other, but that doesn't happen. the antenna selection changes, but not the tx band settings so i still have to reconfigure from one amp to the other when i want to change.

obviously i'm misunderstanding something about profiles.....

if you were trying to set up something similar, how would you do it?

(i'm posting here because i use the mac version of smartsdr. apologies if this belongs elsewhere.)

thanks!
