Repeater (ala .NET WEBFORMS) functionality

Is it possible for the inline list to have it repeat based on category. What I have to do now is that I have to copy the same inline list and change the filter. but if I have to make changes I have to reflect that on every copy.

A workaround for this is to have a user-specific choice component at the top of your page, then use a relation to return the right items based on the value of that choice component, then display only 1 inline list.
