To help with some challenges we are having w/ model admin due to CAT's recent nomenclature changes:
add column/ability to deactivate a model (either base or display) so it will no longer show up on the drop down menus
add a column/ability to assign a specific base or display model to an equivalent or previous model (ex: the D3(new)= D5K2 & D5K or the 140(new) = 12M, 12M3, ect (countless other examples)
ability to assign and manage s/n prefixes to a sales/price, base and or display model
Overall the dealer needs to be able to do more w/ model admin, customize it, it needs to evolve w/ CAT.
These improvements or something along these lines are a very high priority for us because CAT's nomenclature changes have already occurred and there are more to come. We currently don't have a great solution, I personally just deal with it as it comes and hope for the best.
