Hey Michelle,
The list builder is going through your whole company file looking for items that match your criteria. This can take longer if you have a large company file. We don’t have a way yet that will allow us to stop the actions in the middle of running. If you want to do a search and omit Customer:Job you will see on the customer table we have a field called SubLevel. When you do some customization to include omitting clients, use this sublevel.
I was thinking of your question about have a customer with an estimate but keeping them as a lead. Currently, once a lead is moved into QuickBooks because of a Invoice or an Estimate, this lead has now become a Customer, hence, un-checking the “is lead status only” checkbox. If you have a lead and you create an estimate, this customer is going to get put into QuickBooks because the estimate is going to QuickBooks. If you use the option "Waiting for sync approval" on the estimates page; this will keep the estimate out of the QuickBooks and your lead customer out of QuickBooks. This is one way you can go about it. The other would be to customize Method to keep track of leads even if a lead is moved into QB. You could use another checkbox for “Is Lead with Estimate”, this could keep track of your leads. If you do this keep in mind you would manually need to uncheck the checkbox.
As for the picture in email activities, I am still looking into this for you and should have an update later today.
Hope this helps you out.
