Mmm, you might be SoL. You could try a later IOS release (if there is one) and see if that affords any additional configuration flexibility. You could ask TAC. There is a chance that in practice it does not in fact matter but I'd test that one thoroughly and assume nothing. I don't have experience with that TW product.
Suggest you hit up the Cisco-NSP list as it's probably a better topic for there.
