lib/lists.def filter by Subject?

I want to shuffle all messages for "SOMELIST" (case sensitive,
anywhere in the subject line) into a mailing list archive.

How can this be accomplished?

% man procmailex 

shows that procmail supports ^Subject  filtering but

% bin/mk-procmailrc -man

doesn't indicate any method to trigger that sort of
procmail filter through lib/lists.def.

Is there some method to do something like the following?

PROCMAILCONDITION: * ^Subject:.*SOMELIST.*


Thanks,
