Question about the Sales Cadences, we have a branch on our calls, and if the result is Left Voicemail, the Sales Cadence continues, if not, it ends.  Well if a user just marks a step complete, and doesn't actually make the call, the Sales Cadence ends.  Is there a way to enter a blank value to add to the Left Voicemail mapping so it continues in the sales cadence, or make it so when clicking the complete button on the step, it continues down the sales cadence?
