Conversion of foreign design feature endorsements onto Australian CPL

[Benviv]

I hold an Australian CPL and recently got back from the US with an FAA private certificate. I would like to convert the design feature endorsements I got in the US that are not on my Australian licence but have struggled to find a way to do this, if it is even possible.

An instructor friend of mine contacted a CASA inspector in regards to this and he said I could do it using Form 61-4A, I called CASA to ask about the form and they told me I could not use it to only convert foreign endorsements.


Does anyone know a solution to this?

Thanks.
