How to change links for buttons in ST300, ST305N, ST310N, ST315N, ST320N, and ST330 blocks?

If you are using the catalog, there is no possibility to assign your own links for buttons in ST3** blocks from the “Store” category. In this case, you can only select actions for buttons: add to cart or view full product info.

If a button with the "View full product info" action is added in the block, then either a pop-up with detailed product information or the link specified in the product card in the catalog will open (read more about setting up your own link for the product page).  

If you add products manually, then you can specify your own links for one or two buttons, depending on the block.
