In addition to no-class dates for specific classes, it would be useful to have a general list of no class dates for the season that apply to all classes so we don't have to re-enter common dates (like holiday breaks) into all of the classes individually.
There is the option to add no class dates to a season and then they apply to all classes in the season! This is under More > Seasons > Select a season> No-Class Dates on the left side menu. Please contact DSP Support for more help!
