Insights for imported OTB games

I have a file with like 20 PGNs that I’ve been adding to with classical games that I play at my club weekly. I analyze these games individually after playing them, but I would like some “overall” insights if possible. Is there a good way to do this?

Sites like chess dot com and lichess have “insights” features that can analyze many games at one time and provide an overall analysis of your play style, your strengths and weaknesses, recommendations, etc. but they only seem to work with games that you’ve played on the site.

Any ideas/resources? Thanks in advance!
