CMS Load Finsweet "go back" button

Hi all!
The people who worked with “CMS Load”?
Does anyone know the solution…

There is a catalog, there are 100 objects in the catalog, by clicking “Load more” the next 6 objects are opened, and so on.

Problem: When a person chose, for example, a 30 card, went there and returned back, he sees the first 6 cards again, but it is necessary that the number of cards that he clicked “Load more” be opened upon return.

thanks for the help

P.S `javascript:history.back(); does not work, I tested!
