Show a list of assets from which an asset is tagged. So, when an asset is tagged in a field of another asset, you can quickly see from where all the asset is tagged.
For example, if you create Asset A, and have a field "other assets". If you tag "asset B" in this field, and then you view asset B, there is no indication of a relationship. You could also create a "relation" manually, but it would be nice if a relation was automatically created, or if a separate list was show on each asset showing assets from which it is tagged in a field.
