Mitsubishi PAR-40MAAU for Multiple Indoor Unit Control

Mitsubishi PAR-40MAAU for Multiple Indoor Unit Control

My house has 7 rooms and each room has a wired controller for the radiant heat and PAC-USWHS002-WF-2 Kumo Cloud units for the minisplits. I'm wondering if there is any way to share a wall thermostat? I know of the adapter that allows you to wire the minisplit as a second stage to a third party wired wall thermostat but that isn't an option.
