Append ONLY

Append ONLY

Hi,

I wish to upload a spreadsheet, and allow anyone to view (READ).

However, when it comes to WRITE access I want to restrict WRITE access to simply APPENDing further data to the spreadsheet, but not to edit existing data (however it would be very useful to be able to add notes to existing data).

Is it possible to restrict WRITE access to appending only? Can this be done with a Form?

TIA
