Temp card in MagicETL on Preview data

BrettG

I would love an interstitial card builder that I can build on preview data at different steps in an ETL. Often to ensure I'm filtering, or joining as expected I need to run whole dataflows or put aggregates to get counts (and list of unique categories) to check changes or where an issue is occuring in longer, more complex dataflows.

Preview data is clearly logged in a table. A card view that I could insert on an ETL tile that I can create table or bar charts with the couple of columns built just on the preview dataset. Ideally could retain card on the dataflow, but even if just purely temporary would be helpful.
