Hi,
Why not?
Do it like this:
* open the source board file
* "dis none dim hole dril" [ENTER]
* group [ENTER]
* use the mouse to select all you want to copy
* cut [ENTER]
* move the mouse to your desired anchor point, then press the left mouse button
.. now all the selected is in the clipboard
* open the destination board file (without saving the other)
* "dis dim hole dril" [ENTER] ...(just to ensure the layers are visible)
* "paste" [ENTER]
* move the mouse to the desired location, then press the left mouse button.
