How to release top-level VI (only) source code?

Question

Hello,
I am developing an addon to an application I already have. The application is large (over 1,500 VI's) and the VIs are set up to compile with mostly default settings (there's a top-level VI, a few with Front Panel visible, most of them are not visible).
The customer wants the source code to the work I'm going to do, and it's going to use many existing sub-VI's. The addon itself will be a sub-VI (I have a Main.vi that basically opens 'screens', and this is a new screen). The existing sub-VI's basically do the data collection and processing, and the new code will do some additional processing and have a nice GUI to the existing code. The customer wants the source so they can make modifications as needed.
Is there any easy way to provide just the source for the top-level VI? Basically, I want to give them M.vi, where M.vi calls n.vi, o.vi... etc, but o-z.vi need to remain closed-source. Also, M.vi is called by Main.vi, which opens screens A-M.vi
One option is do copy the entire application, then open every sub-VI and save it without Source Code. But with so many files, this seems like a bad idea. I also then have to maintain two applications.
Any good ideas out there? It seems so easy in other languages (use object files) that it seems like there should be a solution here I'm not seeing.... Thanks!

Dont know if this is the best solution for you, but you can create a "virtual folder" in the LabVIEW project with all the sub-VIs that you want to keep closed-source. Then create Source Distribution build specifications in the project and remove the block diagrams assign passwords to all VIs in the virtual folder. See attached pics.
