Suppress InvoicingListDates in customer master data

Hello all!

We only work with invoicing dates and do not use invoicing lists. I would now like to suppress the field "InvoicingListDates" in the customer master data.

I normally do those changes in customizing "Define Account Groups with Screen Layout (Customers)", but in this case i can only set the "Billing period" field (group of invoicing dates and Invoice list sched.) on suppress, required,... ecc.

So i can't treat the two fields differently (what i would like to)... is there any possibility?

Thanks in advance
