enable attachment upload for specific user or sheet

Judotom

Please can you make it possible to enable the ability to upload documents (Attachments) for either specific users or specific sheets.

Currently it can only be turned on for the whole organisation however, this is in conflict with Organisational Security Policies where the ability to do this needs to be controlled to limit the risk of company data being shared when it shouldn't be.

Other service providers can do this however, Smartsheet seem to be behind the curve. Please can you implement this as a matter of urgency
