How to display Outbound Port on Portal

Hi,

We have a requirement in which we have to display different outbound ports of MDM on our portal.

The outbound ports are visible in Result set when we select Advanced Export option, but how can we add a dropdown in the Resultset itself to display all the port values so that the user can select required port as per his choice.

We are using MDM 7.1 and Portal version is 7.3.

Thanks for your help in advance.

Thanks,

Harshada
