Question mixing animations with AnimRigged properties and script handling some of them

Hi, I have been able to develop quite a lot of procedural animations based on scripts / coroutines handling targets that via Animation rigging drive my cat in walk, trot, run and jump. including smooth transitions among them.
I am now facing a problem adding animations that also use Animation Rigging to do some special movements in addition to the procedural ones managed by code. Apparently AR target properties in code are overriden by the ones in animation,
Looking at execution life cycle I thought tyhe opposite would have happend.
Can you elaborate a little on this?
Very nice addition to Unity anyway, really appreciate it.
