Change Payment Terms Config

Hello,

I have a very basic configuration for a payment term.  Net 45 days with a default payment method. No discounts or anything else.  I want to change the days from 45 to 0 and remove the default payment method.  I can't find any discussions or documentation that will tell me if this is feasible.  Can someone in this forum tell me?

I'd rather not create a new payment term as we have custom code that uses this particular PT.

Thank you!
