It would be great if we could set which attachment file types are allowed for attachment
custom fields.
Eg. When using a ClickUp list for external form submissions, our form has an attachments field, but we would like to be able to restrict the file types to .doc, .docx, and .pdf for text submissions, to reduce risk for our team of downloading something unintended/dangerous. Similar for artwork submissions, restricting to .jpg, .png, .tiff
