Timecode staff without barlines

Is there a way to get rid of the barlines in the timecode staff?

i have a vibraphone part with an open meter (X) where I insert dashed barlines at every chord change. I use the timecode staff to add markers every second to give an overview of the tempo.

However, the dashed barlines in the timecode staff are rather irritating. I would prefer a simple one-line-staff with just the markers on it.

You can set this to zero under Library->Engraving Options->Barlines. Will affect other 1-line staffs, though.
