How can I override FCCS_Global Assumptions FX rates for a specific Entity (ies)?

Summary:

How can I load static/different FX Rates to a specific/existing Entity, not FCCS_Global Assumptions, and have them used in the translation calculation?
In HFM, I could load FX rates to a specific Entity to keep a disposed entity FX rates static for the periods for the remainder of the year.

FCC allows me to enter FX rates for a specific Entity (Not FCCS_Global Assumptions) but then it seems to ignore and still use FCCS_Global Assumptions rate for that specific Entity for translation.
