This has been an often requested feature and I have it on my list of features that we would want to implement at some point. Sadly, the way the code is constructed right now and how the project data is set up, it is not a trivial matter to make this change in VEGAS without destroying our ability to read projects from older versions. That is the reason we have not implemented it.

It can be done, but for something like this, it is too much work for us to do when we have many other much more significant parts of VEGAS that need to be reworked.
