What's the Easiest Way to Link a Blendshape with a Material (via Mat Parameter Collection)?

I’m attempting to create a rough prototype that would allow me to check my wrinkle morph work with some very simple static meshes. There is no rigging or weighting involved here, just the mesh and the material. I’d like to use a material parameter to allow a blendshape weight and shader parameter both be driven at the same time, using a simple float value that the two share that I could manipulate with a slider on-screen.

To the point, what is the easiest, most straightfoward way to use a blueprint to connect a blendshape and material together? I’ve been looking into many different tutorials but unfortunately they’re solutions for much more complex setups than I need, or can admittedly grasp just yet.

I appreciate your help and insight.
