I'm pretty sure you can't do this, but wanted to make sure: and also if not, float it as a feature to request. In particular we're currently executing parts of our "disaster plan", thanks to PG&E, but I'm having to manually pipe our performance seating book constituents through an output set that provides emergency contact details.
With a sproc, you could run the report, send its output to a temp table, and then populate a list with that. (Report-to-temp-table is how we customize our season invoices, without customizing the standard renewal notices report.)
