Need Help Setting Up Outdoor audio Spaces

Have 2 zones one Emotiva PT1 Each, and 1 A6 amp, i plan on setting up the sunroom to have 4 speakers in stereo running off the first 4 inputs of the A6 and then have 2 outdoor speakers running off the last 2 inputs for the covered patio. since the covered patio is literally outside, i can’t put the second PT1 out there so i plan on having both zones controlled from a cabinet in the sunroom. the issue is that since there are 2 Pre-amps that are exactly the same… i can’t control them independently. is there a way to fix this? or does anyone have any ideas on how i can modify them such that i can Directly Connect a remote input into them?

Edit: typos, merged the integrated amp name with the pre-amp’s name
