Glass and Water materials - can I stack materials on top of each other?

I have nice experiment with Glass and Water materials here, applied on alembic file import:

I like that dirt feature in glass material!
Can I have these materials on top of each other?
Or even more efficient idea, how can I add this “dirt effect only” to my water material?

Hey Pekka. Have you tried playing around with the dirt node in the Material Graph Editor? You might be able to mix that in interactively.
