Need ability rebuild dimension in Accelerators

While you can upload the template and add new elements. If you decided you no longer want that element the template does not give an options for a rebuild of the dimensions. I suggest adding that as an option, but give a warning that data could be lost. In attached file I added an element(GregLand) and then was surprised that after deleting it in the Excel template it was still there. Now of course I can go into modeler and delete it, but this kind of defeats the purpose of having a system that imports changes.
