Can the supplier site and legal entity default to no value?

Hi,

I am wondering if when users are entering an invoice can the supplier site/legal entity default to being blank?

If it is possible, I suspect it to be a global change or by supplier? Versus a BU setup.

Example:

How it is setup now:

Create Invoice → Select BU → Select Supplier → Supplier Site/Legal Entity default to a value

Desired by business:

Create Invoice → Select BU → Select Supplier → Supplier Site/Legal Entity default to BLANK to allow our invoice reps have to manually select each value.

Thank you,
