How would I detect if they are a member of 'any' secondary usergroup?

<if condition="secondary usergroup != zero> allow attendance </if>

I add/remove secondary groups all the time so listing every group number can be quite tedious using

<if condition="is_member_of($bbuserinfo, X) OR is_member_of($bbuserinfo, Y) OR is_member_of($bbuserinfo, Z)"> allow attendance </if>
