Choose climate target_sensor by input select

I have thermostats in multiple rooms. Until the day comes when i have TRVs in every room to help regulate the whole house, i’d like to designate a ‘master’ target sensor, via the input select drop-down menu, to prioritise a particular room.

here’s my input select:

heating_source_thermostat:
name: Primary Thermostat
options:
- Kitchen
- Lounge
- Bathroom
- Backroom
- Aggregate
initial: Aggregate
icon: mdi:airplay

but really i don’t know what i should do next
do i inject this directly in to the target_sensor line of my generic_thermostat platform, using a value template or something?
or do i use the change in input select as an automation trigger for the climate device?

any thoughts or help would be appreciated!
