How to control two controllers seperate AND/OR combined with K0S

I use two CL2-P75V24 controllers for two adjacent light strips in my kitchen and a K0S remote.
I want to switch them light strips on and off seperately, but also dim them in union.
My hope was to pair zone 1 with strip A, zone 2 with strip B and zone 3 with strip A and B.
But the last step is not working. No more pairing after a controller was paired the first time with this K0S.
Please help!

Dear customer, this remote does not support master group control. Since you have paired the two controllers separately, you cannot link them to zone 3. We recommend you switch to a remote with master group control. If you prefer a panel-style , the B2 is an excellent choice. Thanks.
