Member of SFDC Campaign "contains" smart list operator

Similar to this idea from last year (I'm sure there are probably other similar posts I've missed, feel free to link to them here) -- would love to add the 'contains' operator to the Member of SFDC Campaign smart list filter.

My company uses similar naming conventions for campaigns that repeat (ie product demos etc) and we have several years of history for them in our SFDC acct. Would be great if I could have a filter that says member of SFDC campaign contains "demo" rather than having to manually add 50 SFDC campaigns to the list.
