It would be great if you could use an existing destination as a start for a new one.
use case. For S3 destination, I amy want to use similar data ( bucket name, access keys and so on) but only vary by one or two fields. For instance, the directory location.
It would be handy to make a copy of a destination and only have to change the one fields and save this new instance ready for use. (instead of a re-entering the same data over and over again).
