Overlay on alternate artboard?

Hi,

I have an artboard with a modal popup.  I use the overlay to show this pop which works very nicely.

There is a second modal that I wish to display after the first depending on the end users action.  I would like to overlay this modal exactly the same as the first.  Is this possible?

I did try to move the overlay wireframe to the artboard containing the content I wish to have appear in the background (same as first), but XD won't let me move the overlay wireframe off of the current artboard (which has the first modal).

Worst case, I copy the content I want in the background, but I would prefer not to do this.

Thank you.
