Not available yet, and I made no promises or statements that it would be included. You can post feature requests on my web site. There are MANY feature requests there already (plus many more from direct emails), and there is simply no way for me to make everyone happy by including every possible feature. Nor do I have the time or any kind of incentive to try to do so.
This is far from a simple or quick feature to add, and was not something that our school needed when I developed this plugin. My son has moved on from that school and we no longer use this plugin ourselves, so I donated it to the WordPress community and have already added many more features than we originally had for our school.
Feel free to contribute via the necessary code or financial support donations. Some of the features I have added have been “subsidized” by other users/organizations, and that can always be discussed privately. Also, other developers have recently contributed some features as well, and I’m always happy to accept code from any one who is willing to put in the time.
Otherwise, I make no promises or guarantees as to when, or even if, I will add new features. Sorry, but I have a family to feed, and have to give paid work priority!
