Reload a test into the test builder to make changes to

[abacef]

Is your feature request related to a problem? Please describe.
When creating a test, i save it as, but then I run it and it does not run correctly.

Describe the solution you'd like
It would be great to be able to save an experiment built on the GUI in a representation (maybe XML) so that later a user can load the test back into the test builder and make some changes to it without having to rebuild the test from scratch

Describe alternatives you've considered
I do not think there are any other than rebuilding the test by looking at the code created previously
