Basing a Calendar report on two different event fields

Hi there, 

I have  Calendar report that is base on a Date field called Start Date. It shows all the projects I have scheduled to start each day. 

I have another Calendar report based on a Date field called Initial Appointment. I shows all projects have scheduled to hold calls each day.

Both these fields are on the same table.

I would like to have just one Calendar that shows both, schedule calls and Projects I need to start each day. I would then color code them to distinguish between them. 

Is this possible?

Thanks!
