Hi there @nastonefasto2
Unfortunately no, that is not possible. Please be aware that all remix competitions at Sonic Academy are running for a 3 weeks time frame and unless their was a major issue like uploads problems, this is a fix time. IMHO it's a good habit to set yourself a submission date 2 or 3 days ahead of the official contest ends date when you decide to take part in a remix comp.
Remix competitions & last calls for entries are announced by S.A via their web site, social medias and mailing list, so be sure to check those from time to time to be aware of the latest contest as soon as they pop up. New tutorials are uploaded every Friday, so it's also a good habit to check S.A website on Friday's evenings to see if there's not a new course including a remix competition and to have a chance to get the full 3 weeks time for any contest.
