HR92 and BDR91 on same Zone

Hi

I have just recently installed Ecohome controlling the heating only via 12 zones. 1 zone is a wet UFH controlled by electronic valve and BDR91, 1 zone is a Kitchen kickspace heater controlled by BDR91 and Y87FY. Remaining 10 zones are HR91's with some rooms also connected to Y87FY's.

Is it possible to have a BDR91 and aHR91 on the same zone to provide the following functionality?

Kitchen Zone 1 - BDR91 switches hydronic kick space heater on and off, whilst a HR91 controls the wall hung radiator within the room. Room Temperature controlled by Y87RF. Currently I have the Kickspace heater and the rad on a separate zone.

Thanks

A thought that came in mind was whether l can at least control both zones (HR92 and BDR91) from the same sensor Y87FY?

evohome is quite strict with its applications, so anything outside of the installation manual is not possible.
