possible to post directly to "translated" without being overwritten? (for USD journal in EUR entity)

hi all, I just want to confirm the tool's approach: If I have a foreign entity (defined as EUR), can I post a journal entry directly to USD (Translated), and it won't be overwritten by the built-in currency translation? (in other words, it won't just overwrite translated with whatever is in local?) Or is there something else I have to do to accomplish a USD journal in a non-USD entity?
