UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support A Way to Mass Manage Subscription Dates?

I started taking subscriptions from my members last year.

As an incentive to the early subscribers, I'd like to push forward their automatic renewal date.

Is there a way -- either through 7.3 or the PayPal system -- to mass change a subscription date for members?

For example, for everyone who first subscribed from May 1 - May 31, is there a way to change their subscription start date to July 1?
