How to edit many clips at once?

Hello! I’m new to kdenlive (and to this forum). Is there a way to join two or more clips into a single clip that I could save to my “bin” as a zone?

I’d like to join many clips that sum up to almost 4 hours of video and speed them up to fit into a minute of video. I only know how to do this with single clips. So I imagine if there is a feature to merge all these clips into a single clip I’d be able to do that.

Use a sequence to do that
