At the moment when you save a clip through Render Logical Record, the name remains the same even if you do save another Logical Record. Would it be possible to either add an incremental number after the file name like "Render-001, Render-002, …" or ask for the name each time rendering?
I don't use Render Logical Record that often and tend to forget this annoying feature. Just lost another nice 15 minute render clip today due to newer file overwriting the old. :-/
