Upload textual files to the Arena

[upintheairsheep]

Hello, would it be possible to add text attachments that attach: txt, csv, tsv, xml, html, css, js, py, c , cpp, etc. text based files by having it appended to the prompt possibly bypassing the character limit.
Example

Hello LLM!
———User Attached file: Hello.txt (TIMESTAMP)——
Hello World!
—End-Of-File—
Similar to repochat

Additionally, creating support for excel documents, word documents, and SQLite would be helpful also code folder uploads like Gemini has.
