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

Yes. I don't want random notifications about saving money for X when I receive money just X times in a month, instead I think the smarter would be letting me define which days the app should remind me.

Describe the solution you'd like

I should be able to define specifically when the app reminds me to save money, for example, each 15th or 30th (ending day) of the month. Or maybe specific days in the month.

How will you/everyone benefit from this feature?

Almost everyone in the world has a define day when they are paid, and I think that is more efficient to just remind me to save money the day I have money instead of each day, this actually lead me to uninstall the app.

Additional context

I think that there should be a "default" reminder day that the user define in the app settings, so no need to define per goal that I should save X day, but there should also be the option to define other day per goal.
