Premiere Elements 2022 Multiple Timeline in same project.

It depends on what you mean by "Timelines".   If you mean "sequences" as used in Premiere Pro, then no.  If you mean "tracks",  Premiere Elements can do many.   What are you trying to accmplish?  There may be a methods of doing what you want.

If multiple Timelines cannot be created in Premiere Elements, I would request that this feature might be added.
