Is it possible to have a field visible on the customer portal, but not on the software/agent side?

I would like to roll out a new screen I have created. Upon testing though, it looks like it has removed all the custom field on the customer portal.

Is it possible to have custom fields appear on the customer portal using 1 create screen, and using that same screen, to have a different view on the "internal" agent/software side? 

I don't want to create a new issue type just for customer portal requests, and I would like to use just 1 screen.

I know there is also the tabs at the top for the internal side of the screen, but wanted to avoid using those too, but that might have to be the last resort.

Tom,

I only know of the other way round, where the JSD admin hides a field so that customers do not see it, for example, assignee field.
