Supplier Registration UI

Hi Experts,

I have a question concernig Supplier Registration links:

Although SAP Sourcing provides users 5 Supllier Registration pages to customize in page customization and displays those 5 in reference guide ( default, u2, u3, u4 and u5), i would like to know if there is the possibility to have more pages, and if so, how many more? We´re using version 9.0.09.

Thank you,

Eugénio Caldas
