Can the select a mech menu be a check the box style of filter.

[HyaeksVers]

IE: I want to filter for ONLY advanced rules and tournament rules at the same timeso being able to tick both or something would be cool vs only being able to select one rules set or the other atm
TLDR: is there a way to make the drop downs have check boxes and filter by multiple filters at once vs a single filter at a time.
