Single post in reminder to use a new shiny charm

I would definitely appreciate this since I have now several times on summoned legend hunts realized that I hatched a full/partial party without realizing my shiny charm expired sometime since I last looked. It seems a little odd that there are available notifications for so many other things including the Albino radar and yet this other hunting staple is excluded from it. I hope this gets the needed support to be added in the future.
