multiple network diagram views in same project file

My customer wants to be able to see the baseline in a network diagram view and then switch to the current plan in a network diagram view without having two files open.

I can't figure out how to do this, if it is even possible. There are other diagram views, but none mention baseline.

We can't add the baseline start and finish dates to the boxes because all the fields are used for other information.

Aside from having two files with all the same information except for one having baseline dates and the other having expected/actual dates, and creating a huge CM nightmare, does anyone have any idea how to do this?

Thanks in advance!

My supervisor figured this out.
Instead of using the descriptive network diagram and rearranging the boxes again, there is the ability to copy the network diagram. So we copied it, renamed it and reformatted the boxes to show the baseline info.
