How to access the setting Page for a datafield?

Hi,

i have an Edge 840. I maked a datafield for it and exported the prg file to the Edge. The datafield itself worked fine. But how can i access to the setting page? Its just a simple one for the FTP number. In the Simulator i can access via File > Edit Persistent Store > Edit Application.Properties data. On the Edge normaly i will asked if a want to edit the settings when i add a datafield from the iq store. But it doesnt when i add my own datafield and i see no other way to get access there.
