Can't able to open an image outside of "Pixel Studio" file

[PhilMinecraft]

I can't select images outside of "Pixel Studio" file, unless I paste it all of my works inside of the file, which is very hassle also, it's increasing my memory while copying all my works inside the file and I'm saving my Pixel Art work, can you please add a feature like "Save" and "Make a Copy of Artwork" so it will be less increasing of my memory, and also, pls enable that I can select images outside of "Pixel Studio" file, I have no any pc on my own so I'm working all on my phone.

I also have this problem. I need to edit files where they are, not deal with moving them around.
