[nsp] mrtg and ATM subinterfaces

Has anyone come up with a way to have MRTG monitor traffic on ATM
subinterfaces without having to manually fix the mrtg config every time
you add/remove subinterfaces or reboot the cisco?

The trouble is, as we add subinterfaces, they get numbered as:

interfaces.ifTable.ifEntry.ifDescr.19 = "ATM1/0.7-atm subif"
interfaces.ifTable.ifEntry.ifDescr.20 = "ATM1/0.7-aal5 layer"
interfaces.ifTable.ifEntry.ifDescr.21 = "Virtual-Template1"
interfaces.ifTable.ifEntry.ifDescr.22 = "BVI1" Hex: 42 56 49 31
interfaces.ifTable.ifEntry.ifDescr.23 = "ATM1/0.8-atm subif"
interfaces.ifTable.ifEntry.ifDescr.24 = "ATM1/0.8-aal5 layer"

When we next reboot, I'm assuming ATM1/0.8's entries will move up before
Virtual-Template1 and BVI1, changing their snmp ids. Since there are no
IP addresses on the subinterfaces, I can't have MTRG find them by IP.

Has anyone come up with something better than periodically regenerating
the MRTG config, matching up ATM aal5 layer subs with their snmp ids?
