Thanks! I hear what you are saying.
My predicament is that some of our reps have ~2000 Leads. Even inside of HubSpot, I can select several Leads at the same time, but I don’t see how to use that to change their Stage in bulk or even delete all Leads and just start anew.
As automation doesn’t seems to be a solution because there is nothing currently in the Leads itself that can be used to trigger an automation, and we can’t bulk upload info into HubSpot, I am hoping you have any other ideas 
How would you change thousands of Lead Stages in the most effective way?
