This may be more of a question about how operating systems work. It's not something Formidable controls especially on an iPad. The feature your asking about is built into iPad OS. Formidable's upload field is driven by the JavaScript dropzone.js library. I've scanned the documentation at https://www.dropzone.dev/ and couldn't find a reference to the iPad behavior you describe. You might have to ask someone that knows your desktop operating system if there's someway to automate an upload after a screen capture using a macro or automation tool.
