Simply create a list for each contact you would like to call.
You can also tag existing contacts in your account with a unique tag that describes the list you are creating. Import this list using the 'CSV Importer Integration' and select a unique tag that describes the list you have created.
Once you have imported or tagged the contacts, in the contacts section filter by the custom tag. This allows you to select the uploaded list of contacts. Next, click on the phone icon next to the phone number to start calling down your list.
While you are on the phone with a customer, the corresponding line becomes highlighted so you can easily track where you are in the list.
