Tag Posts uploaded by CSV - for easy bulk deletion

If you make a mistake uploading a CSV file, at the moment the only way to remove the posts is to individually identify them and delete them manually. Given that you can easily make a **BIG** mistake with a CSV upload - for example, schedule 200 posts out on the wrong social media account - **or even worse, schedule out 200 posts to multiple incorrect social media accounts (including client accounts)** - it would be great if there were additional management options to manage ALL the posts uploaded via a particular CSV at once. This could be done by keeping a record of the posts uploaded by each CSV. Or tagging the individual posts with a CSV reference (name of file and date?) making that filterable, so that you can then present ALL the posts that were uploaded via THAT CSV, and bulk delete them. Additionally, you could filter out only posts that have not yet been published.
