Change verbiage on Appoints display shortcode

I'm trying to reword my appointments page and since I'm using the shortcode
[app_schedule], I don't want it to say OUR SCHEDULE FROM.... but instead I want to change "Our" to either "MY" or leave it out completely. I would like to have the option to add it back in later if I do add on more people to my team. Where do I need to look to modify this or is this something that's going to be added in future updates (crossing fingers X ^_^ X )
