InDesign Server - Specific Dictionary to Port

Hi,

I have an InDesign Server with 8 ports running in one Windows Server. Currently, I have assigned 4 ports for UK client, and 4 ports for US client. Now, I need to configure both UK and US dictionaries in the same InDesign Server however 4 UK ports needs to use UK Dictionary, and 4 US ports needs to use US Dictionary.

Please advise how to achieve this.
