Modulus 10 / CID /DebtorId

Concorde XAL 2.60 seems to use modulus 11 as default when generating CID (DebtorId)

and I need it to use modulus 10. In a macro (don't remember it's name) I saw the "code" for

generating both MOD10 and MOD11.

Anyone knows how to get XAL to generate MOD10 when invoicing?
