You have a project of application A, created without NSM, and the project

is saved in P (a single file, or a directory).
You want to use P as part of an NSM session. Note that this scenario means

that A has some button to select if it runs under NSM or not. Let's assume

that the default is to run stand-alone.
There are two ways to do this:
1. ('Load' and 'New' are disabled when running NSM)
* Start A.

* Load  P.

* Connect A to NSM. Application A will receive a path indicating

  where to save its current project. The actual message is 'open',

  but since there is nothing to open at the given path the only

  sensible thing to do is to put the current project there.

  App. A can do so immediately, and then continue as normal.

  The whole thing amounts to a 'Save as' [*] with the name given

  by NSM instead of the user. So it's really nothing new.
2. ('Load' and 'New' are not disabled but the application knows

    how to handle then when running under NSM)
* Start A.

* Connect A to NSM. App. A will receive a path indicating where to

  save the its project. Since A is now running under NSM, it remembers

  this path as the 'current project' even when it loads another one,

  or creates a complete new one (under these condition A is allowed

  to have 'Load' and 'New' menu entries).

* Load P. App A knows that it should not save to P, but to the path

  given by NSM. To keep things simple, it could copy P to that path

  immediately and then continue as normal. Again this is essentially

  a 'Save as'.
The only difference between the two is that in (2) the second and

third steps are swapped. 
No 'manual' user action is required in either case.
Ciao,
[*] 'Save as' interpreted as most apps would, not as Ardour does it.

In Ardour, 'Save as' does not create a new project but a snapshot,

while setting the current name to that snapshot.

It's also a pipe-dream, founded on self-delusion, nerd hubris
