VCS / GIT Integration remove/change

Hello,

i don't know why, but i have a brand new project (wordpress-installation) and i would like share only a plugin into the wp-content/plugins/ folder.

After i trying to adding this plugin as git-project with branch 1.0 the complete phpstorm-project will be pushed (includes all wordpress-folders and so on).

How can i change the git-root on the plugin-project-folder only?
