That is currently the only way to do it.

At Yahoo!/GeoCities we had hosts with names like www123, mail345, so
this selection of groups was easy with something like

(www\d+)

If you don't have this naming scheme, it'll be harder.  You could still do

([0-9a-mA-M].*)

in one config file and

([n-zN-Z].*)

in another to subset them into half the alphabet.

Right now there's no way to do this, unless you want to patch Orca to
handle this :)  I gladly accept patches.

Best,
