In Jenkins job we can add many dynamic parameters.
If we want to have command description for all the dynamic parameters, it is not possible in Jenkins right now.
If I am trying to get ten different dynamic parameter from user for a job which has common description then I need to add same description ten time which doesn't give a good feel in the UI.

So we need to enhance our Jenkins UI so that we can group few parameter out of all the parameters and can have a common description of the same.
