Is there any way around having songs lock after 2 weeks?

[[Member gran…]]

I have been using Smule for the last few months to record videos for remote church services.  It has worked great...but songs locking too soon is sometimes an issue.  I am looking at doing a larger project for Christmas but the 2 week deadline will make things difficult.  Is there a different subscription or some other work around to extend the time allowed to work on songs?

Thanks!
