Blinky Light Loop on Center panel available with limited fabrics?

i want to order a custom built messenger and i wanted one with one of the "limited' fabrics in the center panel. on the builder, when i select a limited fabric it deletes the clip holder for a blinky light when commuting, i was wondering if this is just logistical or if i were to have a custom panel in the center it would indeed delete the loop for the light to clip to.
