How to program prohibitions in summed pricing ACBC surveys?


is it possible to implement prohibitions in summed pricing ACBC surveys? For example: a 1 Liter bottle of a brand of water should never be more expensive than a 1,5 Liter of the exact same brand with identical other features. Of course the 1 Liter bottle can be more expensive, if other features of these bottles vary. If so, how to program these prohibitions?

We really appreciate your help!
Thanks a lot in advance

ACBC doesn't allow prohibitions involving summed pricing since the summed pricing attribute does not have specific levels (the interface for prohibitions requires you to put level X and level Y are a prohibited pair).  You can have the 1.5 liter level add a price adjustment so that on average it will show at higher prices, but you need to have the random shock as well.
