Piled up cards -- add-on to space cards out over a period of time?

I fell behind on my reviews after my last final and have accumulated 2500 cards to review in one sitting. Is there an add-on which can help re-distribute the cards over a set amount of time so that I can get through them but not all in one sitting?

The AnKing posted a video on YouTube about this, here.

You can also use an add-on the AnKing team developed called Weekends & Holidays, but you must be a paid member, which you can learn more about, here.
