Feature Request: Linked Layer Trimming or Trim Point Linking

Allow the In Point or Out Point of one layer to be linked to the In Point or Out Point of another layer, so trimming one layer automatically adjusts the linked layer's corresponding point.

"Linked Trim Points" — the ability to link arbitrary layer trim points (In/Out) so that moving one trim point automatically moves another.
