[c-nsp] Unicast RPF groups?

Is there a way (that I'm obviously missing) to configure URPF interface groups?

Particurally on edges, there's several places I'm using loose checks,
where the real intent would be to do RPF check across 2 or 3
interfaces, ie.

int gig 0/0
  desc edge
  ip verify unicast source reachable via rx group 0
int gig 0/1
  desc edge
  ip verify unicast source reachable via rx group 0
int gig 0/2
  desc local network
  ip verify unicast source reachable via rx
int gig 0/3
  desc internal transit
  ip verify unicast source reachable via any
