Automate parameters inside ReWire client

[osflaa]

I use FL Studio as ReWire client in Reaper. But I haven't yet figured out how to automate parameters inside FL from track envelopes in Reaper. The only parameters from FL available in Reaper seems to be bypass and wet. It works fine to assign controls in FL to an external midi controller and record/playback automation inside FL.

Maybe this is a feature that ReWire does not support? Can anyone confirm or deny?
