No feeder class configurable

Hi,

I want to adapt the GRC application. The goal is to fill the values for role name, system etc. automatically.

For this I create a component configuration for the UIBB which displays the parameters role name, system etc:

Now my idea was to create a feeder class to fill all the parameters (except process and subprocess) with fixed values via a feeder class. But I can not do this, because I have no possibility to define a feeder class. If I click on "Configure UIBB", the following screen appears:

How can I fill the parameters with values automatically?

Thanks and Regards

Peter
