Logi tables merge issue

I had some tables lost for some strange reason but was able to recover some through backup server with dba help not immediately but after a few days. Between the time the tables lost and recovered, I've created new analysis, added new tables in Visual Gallery, so my question  is if there is a way to merge the new tables with the recovered tables? Is that tool called Gallery to Bookmark migration Utility? Also which version of Logi has it?
