v50/s40 MY05: cupholder question

hello, sufu was unsuccessful, or didn’t bring the desired result. I forgot to ask if it is possible to replace the rather “short/niedriegen/untiefen” cupholder from the MY05 with a deeper one? With a c30 car hire (MY 08?) the cupholder was deep enough not to drop 1 liter water bottles in the curve and not to push them out even at random when switching, which unfortunately happens to me more often with my v50. The rubber ring is also not the yellow one of the egg, because only 0.5 bottles fit in. has someone retrofitted his little one? and if that works: what does the exchange cost? best thanks and just greet, sascha
