Our school links Campus to our Infinite Campus grading system (for the first time this year).  Each of my class period consists of several different IC sections due to IEPs, gifted, ESOL, etc.  I want to combine them all into a class period when grading - ex: 1st Period.  Can I add a 1st Period section to Canvas as well as their current IC section (automatically created) or will they see double announcements or double assignments when I post things to "Everyone"?
