[feature request] Being able to personalize the event label

[Just-Regis]

Currently the app allows you to add several dates and choose between "birthday", "other anniversary" and "other", but you can't personalize this label (to add a "wedding anniversary" for example). I think it will be nice if we can personalize this label.

Moreover, if Simple Calendar could retrieve this label when importing, it would be the icing on the cake ! 👍
