A desired function?

Dear all developers, I’m an Apple product fan for about nine years. All my electronics, such as iPhone, iPad, macbook, AirPods, etc, all these are my usual belongings for every day. However there’s always a frustrating problem about my photos. I’m a piano learner/lover and without doubt I need to view music sheets which have been edited and saved in my photos…..then I got hundreds of photos in my iPad and actually every time it takes me huge amounts of time to catch the sheets I need!!! Is there any “rename” or “text label” function for every photo so that I could search the name and quickly locate ???  I sincerely advise that would be developed in the near future. Please be so kind as to see to it that my suggestions would arrive at the development department…..Thanks!
