How to add blueprint variable in Widget Header Button scope?

@Erwin Hogeweg

Hi,

I have a blueprint Dynamic Table widget that shows all the log msgs for the selected blueprint device. I am adding a Header Button to clear all those entries at once, instead of having to click the delete button on every line.
The challenge is to put the blueprint device in the scope. It seems that the scope only accepts constants.

Any suggestion is greatly appreciated.

Cheers,

Erwin
