Adding Overlay over 2 boards

[Warbear]

How do I manage to add an Overlay over 2 boards?
See AP126: "RR8 on 38AA1-56Z10"

You can usually extrapolate to what one of the hexes would be if it was one board, for Example: 38AA1 - 38BB0 (or 38BB-1, or whatever).

I seem to remember doing that in the past?

Try using the overlays extension and you can just drag it into place, too.

Thx for the replies.
Using the number of the corresponding halfhex worked well.
Will try out the overlay extension later ...
