is it possible to source component from specific supplier from specific assembly?

Summary:

Hi Guru,

there is a requirement from client for the supply planning, here is the requirement:

we've set up sourcing rules for source component Item RAW001 from supplier A and B, 50% for each of them, but the client mentioned there are some exceptions, if the dependent demand is coming from certain Assembly item BOM, then system should only suggest to buy from supplier A.

is there any way that we can do this in system?
