Ho do I insert a time period?

I need to insert a 5 min period in the middle of an existing project. How do I make all the waypoints shift 5 min to the right at the insertion point?

The most simple would be to splut your projet and reassemble it un a Non Linear Video Editor.
Otherwise you could insert 2 keyframes zt the split point (pre and post), then extend canvas duration and move tje post keyframe.
I didn’t do the test
