Increase in Scope Mate 500 GRT Oceans to Mate 1600 GL/Inland

Has anyone done an Increase in Scope from Mate 500 GRT Oceans to Mate 1600 GL/Inland? I didn’t realize that I qualified for Mate 1600 GL/Inland when I got my 500 GRT Mate endorsement. I know that you can upgrade from 500 GRT Oceans to 1600 GRT Oceans without further testing. And you can also upgrade from 500 GRT GL/Inland to 1600 GRT GL/Inland without further testing.

But will NMC require the full test if going from 500 to 1600 and changing routes from Ocean to Inland?

JD Cavo would perhaps know the answer.
