The new native SDK FT system only supports the Unified Expression tracking standard. Avatars built with other standards are stuck manually setting 120+ dropdowns in the avatar descriptor.

Please allow the Auto-Fill Blendshapes button to automatically re-map the other tracking standards to Unified based on this spreadsheet created by ADJerry91 https://docs.google.com/spreadsheets/d/118jo960co3Mgw8eREFVBsaJ7z0GtKNr52IB4Bz99VTA/edit

Obviously the results will not be perfect, but it would be a massive QOL improvment over having to do it manually.
