Incremental Insert Freezing

It would be great for example, to select the first 4 inserts and freeze them. then add some more inserts, freeze those, then add some more inserts, and so on.

This could be done form the inserts section, or when the user selects freeze track, a new dialog could appear with ‘All’ or user could make individual sequential selections. Doing multiple track freeze would negate this of course, unless, all tracks could be compiled into the new dialog and the user would have to go through and make selections for each track.
