Apple, PLEASE add a “Select All” option in a search filter!

Apple Developers - please hear me! I have over 80K emails and trying clear my inbox without deleting the few hundred that I might want to keep is extremely labor-intensive. Yes there is a select all for the Main inbox but after you do a search on Sender, there isn’t one, and you literally have to swipe through tens of thousands to select them and delete them. We are now on the iPhone 15 I believe? This option or feature should’ve been added to the iPhone LONG AGO!. What’s worse? It’s not even available on the iCloud email on a computer!
