Cabling Electrical Parameters Dialogbox settings

When I add Connection Parameters that I want to have displayed in my Electrical Parameters Dialog box, they are saved for the whole creo session. When I close, and launch Creo again, I need to add them again.

I tried saving my customization.ui file but unfortunately no joy.

Is there a way to save this model tree settings for these specific cabling dialog boxes.

I am on Creo Parametric 9.0.4.0
