I know we can create a distrubution list using Labels.
I suggest the following feature:
Select customer by a label , but exclude the customer that that have also another Label
Customer - Labels
ABC - LEAD ; Spain
XZY - LEAD ; Australia
CNN - LEAD ; UK
I this example I would like to create a list with all customer with label "LEAD"
but excluding all customers with label "Spain"
To have a distribution list made by the customers:
XZY and CNN
