How do I create a dynamic instance of a post process material?

Is it possible to create a dynamic instance of a post process material?

I have a post process material I’ve set as blendable in a Post Process Volume and I wanto to be able to change dynamically some of its parameters from some blueprints in my project, but I can’t find how to access the array of blendables of the Post Process Volume through the Level Blueprints.

Oh, ok, the Post Process Volume reference node has a property called Settings, which contains the Blendables array.
