Ability to run/test a query from server-side sql action

I’ve seen a number of feature requests around being able to copy and paste the sql create by the ‘regular’ database action (single query, paged, mulitple records, update, delete), however there is a neat feature in the custom query builder that I’d love to see extended to the prebuilt-ones: that of being able to run the query and view the ouptut. Like a test button - we had something similar with dreamweaver. It’s very handy during development.
