Is there a way to save and load a savinglist to webgl?

When saving to webgl with your saving system it is only loading the last game. Is there a way to add the different games to the saved list? It is saving a new idbfs catalogue for each new game I am saving.

IndexedDB lets you store and retrieve objects that are indexed with a "key." All changes that you make to the database happen within transactions. Like most web storage solutions, IndexedDB follows a same-origin policy. So while you can access stored data within a domain, you cannot access data across different domains.

Thank you kou-yeung. I will try to find out how IndexedDB works.
