Let’s consider adding elements from a sequence to the Media Placeholder of any preset using the VHS Pack as an example.
1. Select items
With the left mouse button pressed, select objects on the timeline. It could be anything, videos, photos, text, and any elements together. 
2. Create a new Nested Sequence or Subsequence
Then right-click and select Nest. This will create a new Nested Sequence, and all objects will be moved to this new sequence.
