"On Call" name on schedule?

We are just starting to use OpenEMR in our 2-physician surgery practice.  It is very handy to be able to pull up my schedule for any day I want to look at.

On our paper system, my assistant would type the schedule for the week as a word processor document, and send it to my Android phone.  She would include, for each day, which one of the 2 MDs was on call that day, and whether we were covering any local ERs or not.  Is there any way to incorporate that info into the OpenEMR calendar?
