Yes - this is possible. It's hard to explain in writing, but here's a base that you can copy with automations that create the different events and dates.
Basically, you're doing kind of like an Order Line Item thing where you have multiple individual events that link to an Event Series. So you have an event series that meets once a week for 5 weeks (I used occurrences instead of dates but you could of course use dates if that works better for your workflow) or an event series that meets every 2 weeks for 3 weeks or whatever, and then there's a List of Events table that links the events to the series and populates the dates.
If you don't want to copy the base but just want to get a sense of how it works, here's the form and the Events List table that populates from the form. For using the form, you need to know that weekly events meet every 1 week, semimonthly events meet every 2 weeks, and monthly events meet every 4 weeks.
Hope this helps. Oh, and I need to add a mandatory "yes, this probably would be better to do with a script" disclaimer but I am not at all good at writing scripts.
