Accessing from multiple SourceControl locations.

I recently had to access code from "Sourcegear Vault" and at the same time access from "Visual Sourcesafe". This caused a problem to me as we can have only one default sourcecontrol in Visual Studio. Fortunately, one of my friends directed me to this place ,
where I found the an app that changes the default sourcecontrol in Visual Studio in oneclick.

I however have to remember to do it, before I access projects from the respective sourcecode locations.
