Remember unit test executable used in last run when running tests through the testing plugin

I have a setup where qtcreator is not able to guess the exeuctable to run for testing. As a result, I get a dialog which prompts me to select the exeuctable to run. This is useful

However, qtcreator forgets the selection which I perform. This means that every time I select a unit test to execute, I have to redo the selection in the drop down menu

Since I do this several times a day, this becomes really annoying. It would be useful if at least the last selection would be remembered. Even better would be, if this could be set somewhere in the project settings and it would be used from thereon such that I don't have to do any additional clicks.
