Multiple dates in the ICS file

We organise workshops at irregular dates, where our students can enroll for all at once. The requirement I have is to put all the dates of the workshops in the ICS file that can be downloaded or sent by mail. I tried the extra dates plugin, but these dates do not appear in the main ICS file.
Is it possible to achieve this?

Thanks for any suggestions,
Frans

Hi Frans

The question here is how users register for all dates of that event in your case? Please let me know so that I can understand more about your setup and see if we can come up with a solution

The users register once for a series of workshops. There is one payment for all. The workshops are held on different dates.
We set the date of the first workshop in the event, and the other dates in the description.
We don't check tickets in this case, use only the registrant list at the workshop itself.
The only requirement is that the registrants are informed of the (irregular) set of dates & I would like to offer them an ICS file for that.
I tried setting up child events, but the dates of these events don't show up in the ics of the main event. So, I am looking for other ways to inform our students.
