WTH can't I duplicate a page/tab in my Lovelace dashboard

Working with the Mushroom Theme, Chips, Navigation and vertical stacks I is quite cumbersome to add a new page using copy/paste in the Raw Configuration Editor. Having a duplicate page button would easily allow for creation of meltable tabs once the initial structure for the page is done.

Thanks
