Button Text Formatting

A couple of Button text formatting questions: I can’t seem to figure out how to set the alignment to center. If I use single line, the text starts at the top of the button. If I use two lines, it starts along the bottom of the button. Scrolling isn’t working either.

I did see scrolling working on the actual surface. It doesn’t seem to work in the editor. Am still curious about position of text on a button. Is that fixed such that I need to design a graphic externally?
