Ability to apply multiple styles + better style management

Which device are you using?
iPhone 15 Pro Max

What problem do you see this solving?
Several style packs I have (Mastin Labs) have a base style and additional styles for refinement of the applied style. The current behavior of applying a single style means that selecting an adjustment style will reset the base style. For example, there is a Velvia 50 style, which can have a grain setting applied to it as a style on the desktop. On iOS selecting the grain setting removes the base Velvia 50 style. 

As a secondary problem, I don't see the ability to delete styles once imported, and it's not listed in the KB from what I can tell. The ability to remove / manage styles would also be appreciated.

When was the last time you were affected by this lack of functionality, or specific tool?
Today. I am testing out the iPhone app with styles, and when in the field either with my camera or via iPhone RAW I will most likely use Mastin styles. (Yes I am lazy.)

Are you using any workarounds or other solutions to achieve your goals?
The workaround is to use the desktop application, or manual tweaks via adjustments. I could also write a quick python script to merge together the xmls into the cartesian product of {Velvia, Ektachrome, Provia} * {WB...} * {Tones...} and repackage as a new costylepack. 🙃

Are you happy to be contacted further about this suggestion or request?
Yes

Thanks for developing this as an iPhone app, it's really amazing!
