Add symbol to show In Collection/Library on Calendar Page

Need a symbol to show the episode/season/movie is already in your collection or not. Similar to that of your Watched symbol with the Check Mark.. Maybe a Disk Storage symbol. When viewing the calendar pages it should be visible and not require me to open the Library to see if it is there already then go back again to the calendar page. Same with once I click on a item and it brings up the episode or movie I have no way of telling if I have the title in collection/library.
