your state authority does not allow you to create your own profiles (you certainly can't do that in Australia)
I am not sure what you mean here ?
You cannot create your own FMS approach profile, load it into the box and let the aircraft fly it.
Some charts don't even have a published profile so you have to create your own
If an approach doesn't have a published profile, create your own 300ft/nm profile (320 for the pedants, or was it 319?
) based on the location of the DME and the threshold elevation and fly it in VS or FPA. Write down each altitude for each nm back to 10nm (or the MSA if higher), confirm your profile misses any limiting steps and down you go. CDAs for the masses.
