Of course :-)

You need to write above files. Perhaps I write a script to
create them automatically from WIND and DEFAULT_WIND (or you
write it?). Structure is:

PERMANENT/WIND/ and PERMANENT/DEFAULT_WIND

Edit and change above file to your projection and coordinates.
Take care: The capital letters are required.

Then run g3.region to re-check it.

In case of interest for others, I will be happy to include your
script(s). Perhaps we start an own

 "GRASS Scripts page"

on the server? Then scripts could be shared with others.

Best wishes
