Transient optiton

[trailway]

Thanks for the suggestion. I appreciate it.

What the user can do now is to just go and manually delete the output file in order to force a rebuild.

The thing I was looking for was some way to tie this "transient property" into the Visual Build UI. I thought that it was a long shot but wanted to ask.

I think that this is somewhat analogous to the Visual Studio concept of Build versus Rebuild.
