Of course! When you are in judging phase, you can change the designers to the 1st place and they will have access to upload new entries. So if you wanna see something about my designs you can change me to 1st place so i can be able to upload and then you can change again to any place you want :)
I'm telling you about make some changes and work a little bit more with my designs because rankings started too late in your contest so i couldn't be able to work with you and get feedback and upload again, but we have time... So if you wanna see something please let me know and you will need to change me for a couple of hours if that's ok with you.
