I guarantee then it come topic that no one will go and select 100 listings out of 10000 manually one by one.
If you have such customers, you should already be able to hire developer and do that for you based on your preference
I'll show you an example.
One user has more than 200 ads, there are users who have more than 1000 ads.
When the deadline for publishing their ads has come to an end, they have to renew each of their ads separately, and now imagine 200 or 1000 ads and need to renew each one separately? Each time you renew, the page of the ad itself opens for you, you need to log in to My Ad account again in order to extend the term of another ad. How long will it take if there are 200 ads?
So why not make a function to extend all expired ads with one click?
To hire a certain person to contact users and, with their permission, update their ads, do you understand what you are suggesting?
