How to Initialize the Enum Value of a field from a Customized workiten (MASTER_DATA) to another new Customized Workitem (CHILD_DATA) to the same Field Name with the same Enum Value

I have created custom field as "Origin Country" which has say 12 nos of Enum Values of Country in a Customized workiten type  (MASTER_DATA) . I have also created same custom field  "Origin Country" which has same 12 nos of Enum Values of Country to another new Customized Workitem (CHILD_DATA).

My Requirement is if I select USA as the enum value in  "Origin Country" field in Cutomized workiten type (MASTER_DATA)  then when I create a Record in another new Customized Workitem (CHILD_DATA) type then the "Origin Country" field will be populated with value as USA ( as set in MASTER_DATA).

I could have achieved this logic had "Value Set" capability for Attribute Customization were working across different workitem type with Dependencies  . The " Value Set " for Attribute Customization works only for same workitem Type.

Can Someone help me on this Please .

Thanks
