Blend between two matinees?

Hmmm I think the trouble i have is that my day/night cycle has many params that are included in the matinee:

These are all finely tuned for the course of the day/night. I feel like what I really need is simply a way to override the values the matinee is controlling via script.

I’ve just tested out overriding one of the values and setting it every Tick(), and it seems to have no affect. Do you know if the matinee ticks after US?
