Same event, multiple dates, but not repeating

I'm wondering if you have a solution to save me time: I have the same event on multiple days, but it doesn't have a pattern for me to use the "repeat" function. Usually, I choose the event and use Save As Copy, then change the date to the new date, but I'm wondering if there is a faster way so that I can select multiple dates and apply the event to those dates. 

Example: Course 1, 3 hours in length (either 9am-12pm or 1-4pm) happens on May 6 (morning), May 7 (afternoon), May 13 (morning), May 20 (afternoon), May 21 (morning & afternoon), May 27 (morning), and more. Normally, I will create this course in 2 versions, morning & afternoon, then Save As Copy multiple times, choosing one later date each time. It's tedious as I have more than 20 dates total for this course plus 2 other courses with a similar number of available dates each. Is there a way that I can copy to multiple dates, like choosing them off a calendar, or even typing multple dates into a box? 

Thanks,
Melissa

I may have just figured this out on my own: under the Additional Dates tab. I will give it a try!

Edit: Yes, this works!!! I could add morning & afternoon versions in the same place, but I include the time in the title ("Course 1 9am-12pm" or "Course 1 1-4pm"), I just did all the morning ones and then all the afternoon ones. This is significantly faster than how I was doing it before. 

Will leave this question up for others who may also be curious. 

Hello Melissa

Yes. Additional Dates plugin eventbookingdoc.joomservices.com/plugins/additional-dates is the right option to use to handle this kind of requirement
