This option lets you subtract two fax lists into one list. This feature is useful if you want to broadcast to two lists at the same time, but want to eliminate any duplicates that may occur between the two lists. If a contact is in both lists it will be subtracted from the end result list. You can access this option by selecting the Fax List Management option from the menu bar at the top of the Broadcast software. Scroll down and select Subtract Fax Lists. The following screen will open:
Select the first list from the top drop down box. If you want to create a new list for the combined lists, check the Create a new list checkbox. Otherwise the contacts will be subtracted from the selected list. Select the second list from the bottom drop down box. When you are ready to combine the lists, press OK. If you checked the Create a new list checkbox for the two combined lists, a new screen will appear and you will be prompted for the name of the new list and you can add a general comment about the list. Press OK to complete the operation.
