Installing game from internet with a dropdown menu

Hi,

I wish to install a game by downloading it with a condition ( the file to download depends of a region ).
So I suppose I must use a input_menu, but I found nothing in the lutris’ doc to make a link between the dropdown menu and a file to donwload from a URI.

Naively i think than maybe something like that ?

files:

  • game : /path/to/cached/download/file

but It is launched before any tasks is done

best regards,
