It would be incredibly handy to have an "inherited" subgroup that "inherits" the Static Contacts and Dynamic Variables from the higher Group/Subgroup .
I use complex criteria formulas to create dynamic groups (mixing both post code ranges, alphabetical groups and customer types) for creation of sales territories. I will often want to create a sub group that adds 1 extra criteria for a particular marketing campaign etc. (e.g. industry) and I would like this sub group to dynamically change if I change the criteria for the group/s superseding it.
I have estimated that if I change territories slightly I may have to manually change up to 50 groups in the current system of recreating each group I can not be sure I have got them all correct.
