Is anyone successfully(achieving downgrade and subsequent savings) processing level 3 credit cards with Sage 100 and Sage Payments?

The integration leaves alot to be desired in terms of requiring toggling between credit card tab and line tabs to expose required fields information.  And once those field/s are exposed, there is no(easy) way to tie the values to existing inventory items and have fields populated automatically.

Would be very helpful to hear how anyone is using the level3 "feature" successfully and at scale.

Thanks.
