how to change VASSAL directory in linux?

Hi,

I’m new to Vassal. I’m using linux (Mint).

When I ran Vassal for the first time,
it automatically created a VASSAL folder
in my home directory: /home/surflut/VASSAL.

Is there a way to parameter where this VASSAL should be?
Or even to change it to a hidden one: /home/surflut/[color=blue].VASSAL?

Thanks in advance for your help!
