Can you add room control/zone control to a heating system after the fact?

[R.O.S.S.I]

We have a standard combi boiler heating system that powers UFH downstairs and radiators upstairs. This is controlled by a Nest thermostat in the hall. When the heating is on it heats all of the house and our UFH isn't zoned so the entire downstairs floor warms up (it's open plan).

Is it possible to add zone controls to heating systems after they've been installed?

Would be nice to be able to set the upstairs and downstairs heating independently at a bare minimum, or even have control over individual rooms upstairs.

I don't need the downstairs split into zones. Just having the ability to control upstairs and downstairs heat independently would be the main objective.

How about remote control TRVs?

Would that not need the system to be zoned already to work? I.e already have the up and downstairs zoned separately?

Yeh but i wouldnt be able to only turn on the rads using this method as the UFH would still come on.
