Saving all open tabs from iOS

This question has been asked before but the answers do not address the exact query. We know that you can access all open tabs on your iPhone/iPad via iCloud tabs in Safari. The question is: Is there a way to "Add Bookmarks for These X tabs"? Yes, you can save them one by one (i.e. open them one by one), but can you open them all in a window and then bookmark them all? I've got nearly 500 open on my phone and it takes me too long to scroll through them to find what I want. But I don't want to lose them. I'd like to bookmark them all, them close them all. That's easy--you just hold longhold the tab icon and the option to close all tabs appears. I--and others-- are looking for a similar action in either the iOS or MacOS to bookmark all those tabs in one fell swoop.

Thanks.
