Saving and Reloading Test Runs (Feature Request)

Something that would I would use all of the time is the ability to save and reload test runs.  I'm often cleaing up messy codebases with broken testing, and when test runs can take a long time a lot of time is wasted wading through the good tests to get to bad ones.  When RM is closed the test runs are lost.  There doesn't seem to be a way to reload runs from the exported formats -- or am I missing something?

Use cases:

1. After a test run, be able to save and reload that run -- perhaps to a file that could be sent around to a team
2. Select/multi-select tests to save and reload.
3. An option to open the last run when the window is reopened.
4. Perhaps a way to segregate passed/failed/pending tests into different 'folders' or tabs as they are completed, allowing to re-run tests by a acting upon a folder
5. Tangently related, but a button or mode that would allow rerunning only broken tests.
