Does maildrop support more complex regexp's than listed in the "tips and tricks" section?

I want to do something like this..

if (
/^(to|cc).*(qma...@list.cr.yp.to|dn...@list.cr.yp.to|qmai...@argus.pipeline.ch)/:h
) { to "$HOME/Mail/qmail/" }

Is this possible, or do I need to do this:

if (/^to.*qma...@list.cr.yp.to/:h || /^cc.*qma...@list.cr.yp.to/:h || ....

The former is the method supported by procmail (actually, as most of the people reading this probably already know, procmail matches ^TO as To: and CC: and a couple other things as well, so with procmail I could do:

:0: * ^TO.*(qma...@list.cr.yp.to|dn...@list.cr.yp.to|qmai...@argus.pipeline.ch) /home/adam/Mail/qmail/

(no, I don't actually filter my mailing lists like this, it's just an example.)
