Multi-split AC constraints

Hello there,

I’ve 5 inside AC units at home but only 2 outside units
One outside is connected to 3 inside units, the other to 2.

But there is a constraint induced by this configuration : I can’t have 2 inside units of the same outside unit to be in a different mode for cold/heat.

I can’t set one to cold and 18°C with the other on heat with 22°C
So I’d like to not change the preset directly from the thermostat card and instead, if someone is changing one, change all at once via an automation most probably.

It is only for heat/cold, I can put fan with everything or dehumidify with everything else but not cold with heat (and the opposite).

Does that make sense? Can someone push me in the right direction?
