Creating a chain of Sequences

Folks - I’m an experienced UE programmer but new to sequencer. I have a specific cut scene where there are multiple versions but the majority of the content is the same. I was hoping to be able to create a set of sequences along the lines of
Play Common Intro Sequence
Play variant (1,2 or 3) sequence (different lengths but leave actors in common state)
Play common exit Sequence

I’m not finding an easy workflow for doing this. I feel like shots and takes might do it but can not see a way to save these as separate things.

Am I trying to do something that sequencer can not do - or am I missing some well know (but not well documented) how to?
