Workflow advice for deleting unused MLV

[silenttapes]

Anyone got a good workflow for deleting unused MLVs?

I used MLVFS and end up grading in Davinci. I would love a way to auto-delete all unused MLVs, and would consider any work flow that allows for it (including non MLVFS). I currently archive the prores 4444s from my final premiere edit but would ideally like to keep the .MLVs as every time I get better at editing I wish I could go back to fix up old projects.

Cheers,
