Why do I have to combine dimensions when using Dimxpert

If I have features that are aligned, and I am dimensioning from the same datum/plane, why do I have to create a dimension for each feature to then combine them? Is there a way to select a plane, then begin selecting the features that will be included in that dimension, and the dimension automatically adds to the count as I continue to select features?  It's kind of a PITA if I have more than 2/3X items that will be included in that dimension.

Thanks,
