Separate "add on" services for specific calendars

Hi everyone!

I am trying to find a way to create separate "add on" services to show only on my calendar scheduling vs my employees calendar. There is specific services only I can offer but do not want to make it "admin only add on".

I was hoping there was a check box to click for what calendars you want to show certain add ons to but there is not. 

Thanks for the help!
