I would like the option to set default payment behavior in Bill Pay. The majority of my bills are paid via ACH and from the same bank account each time. Usually these options do get populated automatically, which is great.
The additional piece to complete would be the payment date selection. Ramp’s ML algo seems to pick up the vendor’s due date printed on the invoice accurately every time, yet the payment date field is almost never autopopulated by Ramp, even though most folks will always choose to pay on (or later…) than a bill due date. That seems like a quick win for overall smoothness and ease of use 
Assume that companies will want to release payment just in time in order to have funds arrive on the vendor’s printed due date.
