Saving analysis of imported games

As a gold member, I can save my analysis of games that I have played on chess.com, which allows me to break off and return to the analysis later.  But when I use the "Analysis" feature to analyze games that I have played other than on chess.com and then imported, I do not see an option to save the analysis, so it must all be done in one session.  Is there a way for me to save and return to the analysis of an imported game?  

It is just a text file. Download it wherever you are when you have to stop and save it on your device or computer. It's ready to go any time you want.

Thank you, notmtwain!  This works and is exactly what I needed.  It does take more effort than the "save analysis" feature that chess.com provides for analysis of games played on the website, so I also have asked customer support if there's a way to use the "save analysis" feature for imported games and will post any useful response. 

Customer support confirmed that for now, notmtwain's solution is the best one.  They also added that chess.com is working on a feature that would allow members (or at least premium members) to analyze their OTB games and save them to their account on chess.com.  However, that is a very big project and they are not sure when it will be done.

analysis is for closers.
