Catalog - Provide the possibility to filter by Type or Symbol

With the A10 SR4 there is a new possibility to define columns in catalog to display default symbol of object or ARIS type. However, it is not possible to filter these columns using the filter functionality in the header of the catalog.

Request: please provide the filtering functionality on both column types (type and symbol). The best would be to create a dropdown box from available types/symbols, in this way can the user also understand what types/symbols are available.

Use case:

All roles of type External partner (own object type, own symbol) shall be found.
