I have searched for this and have com up empty.
In Scheduled Transactions there seems to be no way to handle the US Social Security Automatic Deposit schedule. Deposits are made automatically each month on a specific day of a specific week (ie; the second Wednesday of the month). Have I missed something or can this not be done in the current software?

Unfortunately, the scheduling system is not that flexible (yet). It also seems, that you're not alone with this but we did not come around to resolve it yet.
