Ability to define which headers to use for matching

With procmail, I can define a macros like these:

LIST="^((X-)?(List)(-(id|post|help|unsubscribe|subscribe))?):.*"

FROM="^(From[ ]|(Old-|X-)?(Resent-)?(From|Reply-To|Sender)):.*"

and then use them like so

:0

* $ $LIST(glade-users.lists.ximian.com)

.linux.glade-users/

:0

* $ $FROM(billing@verizonwireless.com)

.misc/

Having just converted a large number of procmail rules to cpanel, I find I'm stuck with "any header contains" or else I have to define several rules to get the above effect. I would love to be able to define header matches like the above which would make my rule sets more specific and more compact which in turn makes them more accurate.
