There is now. The first thing to note about Interworking network
selection is that it uses new information items (cred -- not network
blocks). After a recent commit, it is now possible to specify Roaming
Consortium OI as a match item for these, e.g., with following
configuration:

cred={
       realm="example.com"
       username="user"
       password="password"
       ca_cert="/etc/wpa_supplicant/ca.pem"
       domain="example.com"
       roaming_consortium=223344
       eap=TTLS
       phase2="auth=MSCHAPV2"
}

Please also note that this assumes that WPA2-Enterprise is used in the
network.
