I am trying to configure a portal using biomart 0.8 release and want to set some attributes as checked by default in the interface (for example, the way in which ensembl biomart has transcript ID , gene ID already checked in attributes->features).

martconfigurator (portal view) has a "default" property for each attribute for which I couldn't set the value to "true" since it is one of the unchangeable (black instead of blue) properties. Any clues are appreciated.
