Roll up number values based on multifilter

Any chance that a component could be added that would allow you to roll up a value in a collection (count) that could then be affected by the built in multifilter?

Case would be:

  • All records have a budget amount field.
  • All record budgets in a collection roll up and could be seen in a text element or big number element.
  • When multifilter is applied to limit the records in the collection, the budget amount updates based on filtered records.
