It might do, but it depends on how much code it would take to manage it.
When you go into edit mode, however many bars are used by the pattern being
edited are allocated to the edit buffer, and the original pattern copied
into it. Edits are then performed on the data held in the edit buffer.
When you exit edit mode, the edit buffer bars are copied back into the
source pattern, or assigned to a different target pattern, or lost.
In theory, there could be an undo buffer that tracked all changes to a bank
since it was selected.
But that would use a lot of storage.
A simpler solution would be a bank copy option, that would let you copy a
'starting point' bank to another bank.
Then you could make whatever edits you like, but still have the starting
point to recall later.
With 16 banks on hand, you'd have space for at least 4 bank copies before
you had fewer banks to play with than on P3.
It just depends on how many bars are allocated whether you'd have the space
to do it.

It is a fork of the current OS.
Whether I continue to update the original OS much beyond it's current
position will depend on how popular the revised version is.
No-one else has used it yet, though it will be ready for limited beta
testing soon.
To a large extent, playlist functionality is replicated in the new OS.
Each bar in a pattern will have tranpose, repeat and sync options, just like
the steps in a playlist.
You wont be able to re-use the same 'bar' at multiple points in one pattern,
but to replicate a playlist where you have the same pattern on multiple
steps, you would just need to copy the bar you want to repeat to other
positions in the pattern.
Storage space permitting, it will be possible to replicate any given P3 bank
under the new OS.
