Animate material parent in sequencer so that the children are affected?


I have a scene with multiple static meshes and each mesh is constructed with multiple materials. (Scanned meshes with a lot of texture resolution hence a lot on material instances 5-30) I Would like to animate them in sequencer to appear in certain moments.
I can figure out a way to control a specific meshes materials at once. In sequencer i would have to add a track for every material instance that the specific static mesh has so not good. I tried making Material parameter collection on the master material but then all the material in the child chain is affected.
I even tried to add a box mesh in the level with the material instance parent and adding that to the sequencer but it did not affect the children.
It feel so odd to see that in editor manipulating the specific parents parameter it just works as I hoped but cant get this functionality to the sequencer.

There got to be away right?

Thanks
