Focus stacking for Ipad

Photoshop Focus Stacking feature for iPad is a must!

Im a professional photographer and these days theres no reason for a descktop computer, especially with the combination of the recent M1 ipads pros with lightroom & photoshop apps. 
That being said, there are really essential features that professional photographers use.. Focus Stacking being one of them. Layering & aligning 20-30 photos one by one is a joke. Concedering the price of subscription and alternative apps that are a one time fee that already have this feature for ipad, Photoshop should of released this feature by now. 
Besides.. after paying subscriptions every month for photoshop &lightroom, using another app feels like blasphemy.
