Allowing customers to add tags without enabling full edit permissions

Allowing customers to add tags without enabling full edit permissions

Hello! I am trying to understand whether there is a way to allow portal customers to have the ability to edit a single property (i.e., not enabling full edit permissions for a given object).

I would like to allow our users to create and assign their own tags to Companies (the object) within the portal, but I do not want them to be able to edit anything else.

Thank you!
