I asked this question once and was told No and that one has to nominate the purpose of the skills test in advance. Of course, whatever you can agree with the examiner will be fine
It's a similar situation with instrument training. I asked if I could start on training for the IMCR and then, before the IMCR skills test, change my mind and continue to the full IR. The instructor was a frozen ATPL. He said it can't be done. Could there have been some other reason?
