Create a set from records held in the Metadata Editor
It would be useful to be able to save all of the records that you are working on in the metadata editor as a set to come back to later.
For example, this would be helpful when working on a bound with where you need to work on several records at the same time and need to add links across the records. At the moment, if this work is not completed and we need to return to it later, we would then need to create an itemised set by searching for and adding each record individually. Instead, it would be useful to have a way of pushing all the records in the MDE into a set at once.

In my opinion it would be a useful/helpful option to separately save those records within a set which were pushed by the cataloger to MDE before. Or is there yet a way to do so?
