Possibility to bookmark several sites at once

I would like to make bookmark for several sites opened in different tabs, but it seems it's not possible unless I bookmark them one by one.

I checked in menu and context menu, but they don't show such function.

Is that possible to add such feature in the Browser's next version, so that I don't have to make this process for each tab, please?

Or if the Browser already has such facility, I would like to know how.

Thank you very much!!!
