I would be nice, if this mechanism described in https://webcon.com/wp-content/uploads/2024/11/WEBCON_BPS_2025_Release_Notes_EN-1.pdf dedicated to increase security will be also available for attachments. Usually sensitive data included on the form is also in attachments.
Apart from this functionality, it would be useful to be able to define permissions for individual attachments separate from document permissions, with the possibility of inheriting them from document permissions (as is currently).
