Not as a repeating event, no, not unless there's a trick I haven't heard of. The only way I can think of to handle this would be to create one instance of the event, then duplicate it (as many times as necessary) and change the date for each duplicate. Or if there's any sort of pattern to any of the occurrences - that is, it happens on the 5th of every month, the 14th of every month, the 20th, etc. - then create multiple repeating events, one for each of those regularly-occurring intervals (i.e. one repeating event for the 5th, another for the 14th, etc.).
Regards.
