Customize Work Item screen to add a third party hyper link

I need the ability to add a third party URL as a hyper link in a workitem screen on RTC ccm web. The user should be able to click on it and traverse to the link page. Further, I would also like to pass query parameters i.e. construct it as a dynamic hyper link based on workitem attributes. Pls advise.

For example, I wanted to add something like this: <a href=http://mylink.com:8080/MyView.aspx?userid=myId>MyLink</a> so that it shows up as MyLink in Work Item screen. The user should be able to click on it and traverse to this page. Also, I would like to add additonal Query parameters apart from "userid" shown in the example. THe values for the same may come from work item attributes.

Kindly clarify approach
