Currently there is only the ability to add a column and add contacts (single or multiple) to a field. This causes issues when attempting to control who can view something within a dynamic view. It would be beneficial if there was the ability to add a 'group' to a contact field so that we could 'restrict view by current user' based on group vs individual(s). This is especially beneficial when using Dynamic Views within a WorkApp.
Currently the only workaround we have is to create sheet filters based upon another parameter (column setting) within the underlying Smartsheet which is time consuming when a group already exists and could be automatically assigned within the workflow or form used.
