Animate a roller blind and external venetian blind using UI widget


I have a question,

I’m using ue4 to create an interactive house that has blinds.

I want to create a UI widget that helps me to open the blind and close it.

any idea how I can do this?

I already create a sample you can find it here: FURIOOS, Stream any 3D project anywhere, anytime, on any device

but now I need to animate the blind to look like it open and close in the playmode using UI buttons.
