Support for multiple birthdays on the same day

[MANFahrer-GF]

Hello,
I use Assistant Trash Card to display birthdays. I noticed that it is not possible to show multiple birthdays on the same day. When I try to add a second birthday for the same date, it is either not saved or overwrites the first entry.

Would it be possible to include this feature in a future update? A possible solution could be allowing multiple entries per day or adding an option for "additional birthdays" in the detail view.

Thanks for the great app and your hard work!
