Enabling the possibility to attach physical files to SKT assets (Terms, Rules, etc.)

Based on the experience from our company, having only the possibility to link External References via link is not always sufficient. Our documentation is being stored in several places on several sharepoints to which access can be restricted, thus, our users need to request the access to see a given document. That is why we would like to propose to enable the possibility to attach physical files (Excel/Word/PDF) to assets which need to have the external reference linked.
