Add a bi-monthly option for Recurring Invoices
Currently, the only options are Weekly, Twice a Week, Monthly, etc. There is no option for bi-monthly (e.g, the 15th a last day of the month).
You can set a Custom Repeat of every 15 days, but that doesn't work for months with 31 days.
Bi-monthly invoicing is very common, and Recurring Invoices aren't that useful without this option. Thank you.
