Currently, you are not able to create address subsets in ArcMap. Address subsets may be created in the desktop using the Work Order modules, the Work Request module, and the Customer module.
Open the desired module in your desktop version of Lucity and find the records you wish to include in the subset.
Select the Subset tool . You will receive a dialog prompting you to create or load a subset. Select the Create Address Subset option and click OK.
A New Subset dialog box will open allowing you to enter the new subset name.
You will now be able to load and view the new subset in ArcMap.
