Customization synchronization from two source systems to SAP MDG through SOLMAN

Hello All,
 
How tin we sync the customization from 2 root systems to SAP MDG? Let's instrumentality a scenario.

We bash person 2 root systems ECC_NA and ECC_EU. ECC_NA has 3 outgo presumption and ECC_EU also.
 

1. If we bash the customization sync with ECC_NA then 3 payment presumption volition beryllium disposable successful MDG. If we bash the customization sync again with ECC_EU past each existing outgo presumption volition get deleted and ECC_EU strategy outgo presumption volition beryllium available.
2. How tin we place which outgo word belongs to which system?

Thanks
