Training Days

Would be a good idea if there was a way when editing a training plan note that is attached in the Training Days section that we can attach a new attachment there. Our trainers upload their Session Plans for classes here, and if they make a mistake, they have to do a whole new TD note and attach the new session plan here as they can't reattach the amended Session Plan to the original note with the attachment. This ends up with many extra notes and is hard to wade through and see. Would be great if there was a feature in the training days section to edit attachments to the original.
