Again +1 for this.
I can’t understand how this basic feature is not something in the top priority list.
Except mono-product businesses, it’s not possible to only base goals on the global deal amount.
Our only workaround is to create a Hubspot custom report + weekly export + dashboarding in GSheet to achieve this..
You succeeded in creating custom objects in Hubspot, this feature is way easier because it’s based on already existing deal properties.
