I suppose that you created the blank space (between 3 and 4) with a staff style, right?

Instead, delete the blank region (so that 3 and 4 are directly next to each other).

Then, use the plug-in Create Coda System to get the blank space between 3 and 4.

In that way you will also get the staff group bracket displayed on 4.

This was very helpful! Thank you. Now how can I get rid of the circled sharps? See pic.

Oh...I got it. Measure tool and "Hide Cautionary Clefs, Key and Time Signatures.'

Well, now I don't see the break between my measures in my parts. The "Create Coda System" plugin doesn't work when I have the part open.

You're right.

(But, in fairness, that wasn't the question you asked originally.)

By examining the Page Layout settings for the Coda system and experimenting to "replicate" them on the part layout. I found it possible to simulate what I think you need.

Unfortunately the plug-in Create Coda System does not work in the linked parts.

Instead you have to do “manually” in the linked part what the plug-in does in the score.

And that is always possible.

A plug-in only does what you can do yourself, “manually” - the plug-in just does it faster.

One idea:

Extract the part, and run the plug-in on the extracted part.

Then you can just use the extracted part instead of the linked part.

Or you can examine the system margins in the extracted part, and use the same system margins in the linked part.
