Is it possible to programmatically edit the Version field in the Solution Explorer?

[BertMcMahan]

The Solution Explorer lets you specify a version number for the build you're running. This is very convenient and very helpful, but I'd like to pull some of my versioning info from my SCC.

Is there a way to make a project item that can run "before" the rest of the build, and update the version number?

(It appears that the .lvsln file is just an XML file, so theoretically I could make one Solution that runs a VI to edit a second Solution's XML file then run that Solution within my main Solution, but that seems like I'm fighting the system a bit :))
