I am really confused with your answer.Can you explain ?
Let me preface my clarification by saying that, at least during the time I went through, there was nothing special you had to do during the application process, so that may be where some of the confusion lies. Unless things have changed, you assign your app to be sent to the ERAS schools without discrimination between a categorical vs. advanced spot at that program. If this is now somehow different, then I can claim no special insight into the process.
During the MATCH process, however, some programs have both advanced AND categorical positions. At UWisc, we have one of each, so for purposes of clarity I'll use that model. It may be helpful to think of these spots as two separate programs, each offering one spot. One has an integrated intern year, one leaves the intern year up to you. Once you enter the dedicated radiation oncology portion of your training (PGY-2), these programs are indistinguishable from one another. During the match, UWisc will have two entries for you to rank. As with ANY OTHER situation, it is in your interest to rank them according to your preference. If you see no appreciable difference between the two, you'll likely rank them next to one another; if either the advanced or categorical position holds greater appeal for you, you'll modify the rank list accordingly (in other words, the spots can be split on your final rank list).
With each and every program you rank, you will also assign a rank list of the prelim/TY years at which you interviewed. Obviously, with the integrated intern year of the categorical positions, this option will not be available.
Again, my apologies if this doesn't apply to the current question. Hope things are clearer for you.
