Run a webinar report as of a specifc day?

I want to run a registration report as of a specific day.  For example today is 2/16 and want to see who had registered as of 2/14. We made some changes to our custom registration questions on 2/15 and now the answers to the questions from everyone who registered prior to 2/15 are gone.  I would like to run an as of date registration report.  Is that possible?
