If you load any sequence into your source monitor
You can edit it straight into your new edit timeline using
Command F9 (or Apple F9)
This will edit the original clips into the new edit timeline – rather than the nested sequence
This makes the cutting of a sequence into another behave just like on the avid
FCP call it “Insert Sequence Content”

You can also map this onto your keyboard as F9 if you want

All best
