It would be great to have the option to turn off notifications for specific trainings. If there was a toggle button on each training, course, checkpoint, etc. that allowed us the ability to turn-off notifications for specific instances. Additionally, if this was an option we could set a default option so if we do have a large amount of trainings that we do want to have notifications on for then that could be the default, but then we can change accordingly.
Overall it would be nice to have more options regarding notifications. Such as limiting notifications, turning off over due notifications for specific instances, etc.
