Multiple Unit Testing Projects -- Run all tests, but one project at a time

I have a large visual studio solution with 13 unit testing projects in it. I want to run all the unit tests, but I want to ensure that they run one entire project at a time. Is there anyway to achieve this?

Currently, when I select Run All from the Test Explorer window - I know that they run at what appears to be a semi-random order, where it might run a test from Proj1 then Proj2, then come back to another test from Proj1. The order in which they run is not an issue, the issue is that I only want a single project to execute then move on to the next project, etc...

Ideally, if a test from Proj2 is the first unit test to execute it would run all unit tests in Proj2 until there aren't anymore. Then it would move on to the next unit test, if Proj5 for example -- it would again run all of them within Proj5 and then move on. Is this possible?
