Hello,
Something in the roadmap for 2016
Today, if the same venue, you can use the save as a copy button, when in admin edition page, to get a full duplicate copy of the event, and then edit just the title, description, dates.... so only what is changed.
Of course, it's not the easiest solution, but this one could help until i will work on a new system for venues management (i have already this in mind, and know how i will develop it
)
Best Regards,
Cyril
