It would actually be great if users could select what ranger of inserts are part of the freeze starting from Insert 1.
For example, my first 1-6 inserts are typically static cleanup and tonal shaping inserts.
Once those are set, I could faux-commit to them via freeze, and then continue adding inserts or make use of ones already part of the template.
Then a user could just drag the Freeze designator line bar thingy further down the insert list, and would automatically re-freeze the entire chain and update it accordingly.
It would almost behave more like DOP does.
