Disabling a Custom Player Option

Hi All,

I added a custom feature that displays in the top right corner of the player. I know you can control a custom player option per slide by selecting or deselecting it from the Player Properties. But when I open the Custom section, I only see Resources, Menu, Volume, etc. - but not the feature I added. I thought my custom feature could be controlled as well. Am I mistaken about the ability to control a feature that I add?  

Thanks.
