Generic Link for spend authorized supplier registration

Summary:

Hi All,

Do we have a functionality to create generic spend authorized supplier registration? At the moment customer is copying link from 'Configure procurement business function' and proceeding with supplier registration. This link contains a BU id which act as inviting Procurement BU, Once the registration is approved, a site is created automatically against this BU.

Customer have more than 80 BU and site to be autocreated for all the BUs manually at the moment(autocreate button).

Is there a way to generate a global generic registration link(I do understand that this limit BU level approval since there is no BU id)?.
