Collection Input Jasper Server

How would I do a collection parameter on the jasper server for an input control?

I have a report that I created that uses the java.util.collection option, in testing I enter several sets of codes that I want the report to report on.

But when I go to the Jasper Server input control I don't have an option for the user to enter the collection at runtime. Unless I am missing something?

Let me know if you need more information to assist me.
