Rather than select users or user groups (or entering email addresses) can the option be added to allow sending to a predefined publishing list? (I dont believe this is currently offered).
This is something I was looking into as well. I couldn't find any way of doing this at the time of writing this comment. Hopefully, this should be a relatively easy feature to update for workspaces.
Yes! The use of existing Publishing Lists will be very helpful. Transitioning some scheduled Report Builder dashboards over to Workspace will be less tedious with the use of current Publishing Lists.
If not, simply having the ability to copy a list of emails into the Workspace scheduler would be good. Currently Workspace scheduler does not allow the pasting of multiple emails at once.
