show an event on more than one day in eventcalendar 3

hi there,

I was wondering if it is possible to show an event on more days in the calendar of the “eventcalendar 3 plugin”, without posting (for example) 3 posts when you want to show an event on three days.
I just want to post one message and that you can choose to add it to more dates.
now I just choose the “edit date” option when writing a new message that I want to show up on another date, but then the message can only be shown on one date.
It seems to me that it could be more easier. a suggestion for a better plugin is also always welcome!

thanks a lot for your help!
