Any one implement AP invoice for Mexico now? Where do u save the UUID?

In Mexico, the new requirement is save the UUID, a big number generated when the invoice is stamp from the tax authority, and is more important than invoice number, but invoice number still exist. For report proposal  for the tax authoritity is mandatory to show that id in the ledger information, well in subledger accounting and all others report that the company use, then I choose to use it in the invoice description, then it 's show in the subledger lines accounting.

Any way I want to know if you do it... how u do it... then we can make a document reference to have all the same solution.
