WebStorm with mulitple projects attached - open a tool window for a certain project

I've got a project with four different repositories.

Recently, instead of opening four different windows, I've decided to open up the most important repo and attach to it the other projects.

However, it seems all of WebStorm's tool windows (VCS et cetera) are still bound to the main project, and there doesn't seem to be a convenient way to manage all the projects from one WebStorm instance.

Is it possible to, for example, open the VCS tool window and easily switch it focus between projects?
