Hi Shane, if you are just looking to display the results, you may be able to use a template component, or template fields in a table. Global Merge Syntax will let you pull data from other models and fields and display it anywhere you want.
If your use case is more involved and requires that your aggregations are displayed in context of other objects, you may find this recent post involving UI-Only formula fields and the MODEL_LOOKUP function helpful as you look for a solution that works for you.
