We use our own variation of the Project Management Template Set, and our PMs copy the folder when they are initiating a new project. We would like to include a formula in the project plan template for which the reference to another sheet will persist and work in the copy. This will help so that the PM doesn't have to remember to update the formula to 'add' the other sheet reference. In our case, the 'source' sheet being referenced will always be the same for all project plan copies.
