How to select multiple targets from a list in project outline?

[Alexey Elfimov (ikocs)]

I'm working on a project with many build targets (binaries, libraries, tests). There can be 70-100 of them. I usually use 3-5 of them. And it's inconvenient to search for each one and switch the build to the selected target each time. I can't find a way in the documentation to "pin" or highlight individual targets in the project outline. Is it possible to enable some kind of favorites menu or create a folder within it?
