add tranform file to studyset

Hey Omnisets team! I have an idea that would make Anki even more useful for studying. It would be really cool if we could attach different file types like markdown, PDFs, Word docs, or HTML files to our flashcards. For example, sometimes I want to make flashcards based on notes from a lecture, but the notes are in a Word doc or PDF. It would save me a ton of time if I could just attach that file right to the flashcard instead of having to manually type everything out again. Or say I'm studying programming and want flashcards for key concepts from a markdown README file. I'd love to be able to just attach that markdown file instead of copy-pasting. Plus, you already have the awesome note-to-flashcard feature. Adding attachments would take that to the next level! We could turn anything - notes, docs, webpages - into a flashcard study set by attaching the file. No pressure, but I think adding attachments would really take Omnisets flexibility and convenience to the next level. Let me know what you think! I'm happy to explain more or provide any other feedback if you're considering this feature. Thanks for making such an amazing study tool!
