Add additional action to FileHistoryPanelImpl WITHOUT own VcsProvider

Hi,

As far as I can see there is no way to add an additional action to the FileHistoryPanelImpl (in addToGroup method).

Is that right ?

I see that there is an getAdditionalActions in VcsProvider impl called.

But in my case I want to add a "general" action which works and should be added to all existing VcsProviders (SVN, GIT etc).

Thanks
