Support Portal - Workspace Filtering

I would like to suggest that there be a way for Requesters to filter on the Support Portal as to which workspace (Service Requests), they are after filtering on. Atm, it just shows all the categories in one space and can be a bit overwhelming. If it was possible to maybe show the ICT categories by default and then have a filter at the drop in a Data Source dropdown menu, where customers can then select which workspace they would like to navigate to. That way it only shows them the options available for those workspaces and is not overwhelming or confusing.
