Sandbox Sites

I love the Sandbox. However, even though they have a tag on them they're still co-mingled together. For me it's showing "Dev (3)" in the Filter, but it doesn't say if they're Paid or Sandbox. And, there's nothing in the Tags. Since there's a tabs that says "All site", "Needs attention" "Needs update" - that would be a great place to put "Paid sites" and "Sandbox sites". I know we can use the CSV to download, however, having a way to clearly distinguish or separate out the Live sites from Sandbox right in "My Sites" would be really great.

Unfortunately, it appears that Agency Sandbox environments do not support multi-site WordPress installs, which is something needed to test before committing to that solution for this specific use case

It would be helpful to be able to select the files/folders when copying the environment from development to production. At least the option to exclude folders/files is required.
