When I post all our  Credit Cards on the 1st working date of every month, I have on two occasions had the transactions idle in processing.  The "Payment Processor" is trying to process, but the lines are too busy.  I let the processing go for 7 hours and it still reflects as "Gateway Processing".  I couldn't stop the processing and had to create a transmission file again.  I could run the risk of having the credit cards be processed twice.  If we could send the credit cards through prior.

Example:  on 02/27/2018 I send my credit cards through and have the ability to select a fill in box with a "Due Date" field:  of 03/01/2018.  If I know I'm going to out of the office prior to my processing date,  This would also ease the system from Overload of the lines being overly busy on certain days.
