Don,
Only way I know of is to use the Make Feature option for each measurement so they show up in the Model Tree, then highlight them and select Edit Parameters in the RMB. They will then show up together in the Parameters dialog box with their requisite values.
What's weird is you can do it for Area and Perimeter (see image) but Distance doesn't seem to want to "cooperate". The Measure Distance dialog will return and error stating "Distance/Angle/Transform require exactly two references"

Wish I could have given you a better answer
