How to replicate ECC material ID into C4C Product ID ( internal ) not only un external ID

Hi SAP community

I'm on the initial load of products from ECC to C4C using  PI

i already have some products replicated , but i'd like to know if i can   have the same ID in C4C internal product ID and not only in the external ID field

this only for not  to get the user confused with  two different ID's.

thanks!
