Separating BSDFs, of the same type, to different AOV

Hey all, wondering if this is possible in Karma:

I have a shader comprised of two dielectric BSDFs. The results of each are appearing in the combinedglossyreflections AOV.

I would LOVE if I could make each of the BSDF contributions pipe in to separate custom AOVs.

Reading the docs, and looking at the premade rendervar for SSS, I see there is some support for "BSDF Labels". Admitedly this is a mantra page but I was just trying to get my head around LPE syntax https://www.sidefx.com/docs/houdini/render/lpe.html [www.sidefx.com] and it does say "This can be used to separate contributions from BSDFs that fall under the same broad event category, but have different labels." Which sounds like exactly what I wanted, but I havent been able to successfully stumble into any syntax that does what I want right now.

Do we have any control over what a BSDF label is? or any ability to inspect which BSDFs have which label? Am I down the wrong track entirely?

Appreciate any help!
