Hello,
That's one of the feature in the roadmap.
For now, only the way to open an event with the venue already set, then a click on "Save as a copy" button, and to change only what is needed to be change (date, event title, image...)
About the Venues manager development, due to other major developments in process, it may not be before version 4.1.0 (3.7 will be for registration improvement, and additional pro features like paiement and frontend edition, and 4.0 will be the integration of a full new date system manager, much more flexible).
Best regards,
Cyril
