How do I omit emission component from indirect light group AOVs?

If I have several light groups the emission component of a shader appears in all of the indirect diffuse and specular AOVs, so it adds up incorrectly. Is there a way to avoid this? Really I just want it in one indirect diffuse and one indirect specular. This might be a re-post, I asked this 20 minutes ago but I can't see my question showing up.

Try creating custom AOVs that use the full LPE, like this for indirect light groups 01 and 02:

C<RD>[DSVOB].<L.'01''02'>*

Thanks. This does omit the emission but I'm unable to get exclusive AOVs per light set. If I put C<RD>[DSVOB].<L.'01'>* I get 01 and 02 showing up in the AOV. So I'm still missing something. I want one AOV for each light set.

Can someone respond to my comment to the first answer?

Which was this:
