How to improve batch cloning events

How to improve batch cloning events

Hello !

We have 2 weekly events, I have to setup. I've prepare them in advance for the whole year, that means roughly 50 weeks, 2 events per week : 100 events to clone.
The only change is the date. Time, content, tickets are exactly the same.

However when cloning one event, it takes me 4 to 6 min to clone, remove (copy) from the title, update the time as it always resets to 12am, update the URL and change the date of the ticket sale date (by default 2 days after cloning time).

How can I improve the cloning ? for example auto generate the URL to avoid error in URL duplication, have the opening sale at a future date (like Dec 1 in my case)
It's ok for me to btach clone evenst, then later edit them for correction.

Thanks !
