The one (small to moderate) problem with Handbook Gem Selection...Boxes

(The censor won't let me write the word that starts with "ch-" and rhymes with "vests." 😳)

On the whole, I like them a lot. But in events like Fortune Bag (the point reward collection) and Celebrations (the Celebration Points reward Hot Event) they replaced the awarding of Mount Handbook Gems and Angel Handbook Gems (as opposed to the Adv. version of both) which aren't themselves options for selection from the Handbook Gem Selection Chests.

Speaking only for myself: as much as I like having greater access to the Adv. versions of these Handbook Gems, I was not quite finished maxing all of the Angels and Mounts that used the standard gems.

It's not a problem with the standard Fairy Handbook Gems, because those can be purchased in the Celebration shop for Normal Tokens. Maybe the other two could be added?
