UMG Button widget, how to change its text in another interface widget

I have a interface widget that’s solely a button so I can access it’s On Mouse Enter event, but I have a problem.
I have another widget for the entire main menu of my game that consists of several button widgets.

How can I access the text of that button widget from the designer? Is that even possible? Currently I’m changing the text in the construct event, but that doesn’t seem like the best way.

Here’s what I mean in pictures:

This is the button widget. Only a button + text, nothing more.

This is my mainmenu which consists of several button widgets:

How can I access the text of the button widget in the designer of my mainmenu? Maybe it’s somewhere obvious but I havn’t been able to find anything yet.
