Allow use of saved searches to select elements for tools requesting multiple elements

In many tools in the Main Frontstage\Civil and Advanced Civil tools require the user to select multiple elements for processing. Some of the tools in the Main Frontstage will work using a workaround, although very tediously, by selecting elements using a previous "Find Similar" or Saved Search. However, none of the Advanced Civil Tools allow this.

It would be helpful if the tool would directly allow this method of selected elements, as there are some tools that would require the user to manually select 10s, 100s, 1000s of elements for processing.
