Just to be clear, this should not be a normal activity. ShowMojo is meant to automate your entire leasing process, answer all emails and phone calls, and keep you from doing things like this.

But when you do need to add a showing, you can do this from anywhere in the application by clicking the New Showing button. 

After you add the new appointment info, ShowMojo takes over and treats your showing just as if it had been scheduled by the prospect online.

NOTE: The showing will be created even if the required pre-screening questions are blank or if the answers provided do not meet the Screening Question Restrictors.  ShowMojo assumes you do want to move forward with the showing for this prospect.

And be sure to read about how you can Reduce Call Times with an Automated Pre-Showing Questionnaire Followup.
