Is your feature request related to a problem? Please describe.

Not to forget about upcoming payments or to get informed in advance a notification system would be helpful. E.g. to get notified about an upcoming contract extension allowing me to cancel it or to make sure I have enough money on my account.

Describe the solution you'd like

Have an option for each expense to set a reminder on the day of the expense or maybe also with a variable time in advance to get notified about the recurring expense.

Describe alternatives you've considered, if any

Have an option in the app settings to define a global reminder for all expenses.
