Try this method, Nested Timelines. It will remove the need to Copy and Paste the subbies.
1 – Create an EMPTY Parent Subbies VEG.
2 – In a separate instance of VP open your first and place the Subbies on the TL. Name that Veg anything, try Subbies 1 and save and close.
3 – Repeat until you’ve gone through ALL your Projects and named them Subbies 1 thru xxx
4 – Go back to 1 above and now IMPORT all your Subbies veggies into this Parent Subbies VEG.. you now have ALL your Subbies veggies Nested on ONE timeline in one VEG.
Yeah, I know, it’s ugly, I also miss Media Manager.
