Carryover Losses - Skipped a few years, possible to amend?

There were a few years where I did not file taxes because my income was under the limit. What I did not realize is that once you skip a year, your ability to carryover losses is forfeited. 

 

Is it possible to go back and file those taxes and re-obtain the ability to carryover losses in the current tax year, and subsequent years?
