Hello parentinginnky,
Our Events Calendar plugins do not have a duplicating function, but there are other plugins available that might be able to make that work with our events. You could try our free The Events Calendar with one of them and see if they work together for you.
And shortening the titles in the calendar is not something the plugin can do. Most users prefer the full title. It might be possible to change it with some fancy programming tricks, but it’s not something it can do out of the box. However, tif you’d like to request it as a feature you can add your voice to our Feature Ideas page (https://tribe.uservoice.com/forums/195723-feature-ideas) that would help us in prioritizing it.
