CR creation for Customer Master with multiple Company Codes and Sales Org "at the same time"

Hi Experts,

We are implementing MDG 1909 on S/4 HANA cloud single edition. MDG has to receive customer master data from a third-party system via CPI to create CRs and data enrichment. CPI can send only Customer General data(BP level data) to MDG or it can even send Company Code and Sales Org along with the Customer General data to MDG. Upon receiving from CPI(SOA messages), MDG will create Customer Master CR(programmatically) and later Data Specialist can enter other Org level data(for the Company Code and Sales Org received from CPI) in MDG and further data enrichment and so on....

Now, CPI is saying that, they may send multiple Company Codes and Sales Organizations at the same time in case of CREATE scenario and want to know from us if MDG can handle that scenario(Creating Customer CR with multiple Company Codes and Sales Org in MDG at the same time). I have the following Qs in this regard?

1) Can MDG create a Customer Master Change Request(I know how CR gets created programmatically) with multiple Company Codes and Sales Org at the same time? Can MDG handle such senario?

2) If the answer of the above Q is yes, then kindly tell me how technically....? Will I have to first create the Customer and get it saved in MDG with COMMIT and then again come back and extend it to one Company Code and Sales Org one at a time(in a loop)..OR we can directly create the Customer Mater CR with multiple Company Codes and Sales Orgs? In case of first technical approach(mentioned above), will it not become the EXTEND scenario inside a CREATE scenario?

Request your kind help.
