When I create a custom position with Frisian or Frysk! rules (and other variants rules), the website does not allow me to continue from the position, even against Scan. Furthermore, custom positions are not allowed under such rules when making a tournament.

Will the possibility of creating a custom position with a variant be added ?

The 8x8 boards do not support scan yet so they can not be played against the computer. IE continue position

As for frisian and frysk \_- - _/
