Change Editor Temp folder location

We have our project being managed by Perforce. Right now some files that are copied into /Project/Temp are write only which causes a couple different problems. I would like the Editor Temp folder to be located somewhere outside the project. Is there anyway to point Unity (editor) at a different location then /Project/Temp?

You don’t commit the temp or libraries. They are useless files to commit since they are auto generated on launch if they are missing. Here is a list of things you should ignore.

Pretty surprised there is no answer/solution for this. Seems like a simple setting that should be in the Preferences or something. Anyone know of a solution (or hack) around this?
