Not a feature right now AFAIK. Sounds awfully close to the request below on GitHub:
I guess this quickly spins off a lot of related problems that requirements and a design of UX + code is needed for… like who must be able to delete records - at what granularity should this be managed etc. etc.
So my point is it’s not just asking for a feature like this - you/other people here also have to help dig that level deeper and flesh out what’s needed at a deeper level if something like this should ever have a chance to “become a thing” – in or in relation to Metabase … so … let’s see if a fruitful design debate is possible on this.
I might have something more to say on this topic - later - but for now I would like to kick the ball back
