Someone already asked above question, though. I couldn’t find the answer. I know how to use “prefill function” for text but I want to use it for attachments file. is it possible?

I already know that the prefill form is used for text fields. Can the attachment field be used in the same way?

Is there a limit to the number of items in multi-selection field in airtable? For example, I am wondering if I can make 1,000 or 10,000 items?
