How do I create a textbox in excel that fills a specific range?

Using vba, I'd like to be able to add it and make it sit over a specific
range, like A2:H8, for example. Is that possible?
I know that I could alternatively just merge a bunch of cells and make a
text box that way, but I was hoping for something that would be easier for
the user to move around if they'd like to.
