Andres - Check the help file. There is a section on configuration variables. One of them is a variabl for setting the profile cell level:
GPK_LEVEL_PROFILE_CELL = Level Name
This will force the cell onto the named level. The color, weight, etc. were once upon a time hard coded. But, I think we enhanced it in a recent version so that it takes on the color and wieght of the named level.
FYI - A similar config variable exists for cross-section cells.
