Is your feature request related to a problem? Please describe.
When adding a Poetry environment, sometimes the venv already exists and I just want to register it. But the panel only shows the root directory's environment if it exists and is not yet mapped - I would like this to work when there are multiple Poetry projects in the same repo.

Describe the solution you'd like
I'd like the dropdown to include all the environments located in existing modules that have not yet been associated.

Describe alternatives you've considered
Associating by adding new also works, but it's a lot slower and shows all modules instead of just the ones that don't have SDKs yet. I would like to sweep through and just add ones that I don't have associations for.
