cryptomatte passthrough filter

Would someone be able to make pass through filter for cryptomatte to work with Mantra? Working fine with Arnold, but there are some limitations on Houdini side and unfortunately it will never works as intended unless some modifications are made for Houdini purposes. I did read some stuff on their documentation and easiest implementation would be pass through filter, that would generate only the needed AOVs using material name and (this is important) using custom string attribute (lets say "path" parameter from Alembic).

 

Anyone willing to make that filter?

 

Im using Arnold in similar ways, using one shader (not supporting cryptomatte) to shade, and different shader (supporting cryptomatte) in pass through mode to generate AOVs only.
