publish subscribe - ZeroMQ pub-sub categories: are wild cards possible for multiple subscriptions? -

i have been reading through zeromq documentation , wondering if there way subscribe using wild cards? need system can publish on a.b.c , subscribe on a.*.c or a.b.* ( i.e. subscription on a.*.c match publications on a.b.c, a.x.c, a.y.c, etc ).

zeromq pub/sub prefix matching. a.b.* fine ( match a.b.c in example ).
"inplace matching" not supported, obvious reasons ( subscriptions stored in trie data structure ) [http://www.250bpm.com/blog:19]
