Update which copy of an application?
Is there any way to know and/or control which copy of an application is updated? The Mac App Store seems to looks system-wide, on all attached volumes.
I have 3 boot volumes (one to run 10.7.5, one to run the current OS, and one for develoepr testing). The Mac App Store seems very unpredictable in which copy of an app it chooses to update.
