However, you can do both with pattern match rules:
B0 46-54 00 = XX XX 7F B0 46-54 = XX XX 00 +C
The '+C' rewrites to a clone which gets sent after the original (sometimes remapped) event. We can omit '7F' as the third byte on the left in the second rule since from the rule above, it will always be 7F anyway.
In fact you can also omit the '00' in the top rule too.
