Event date range limit

Hi there.

I was just wondering if there was any way to put a limit on the maximum number of days an event can have when using the events date calendar?

i.e if the max days was 5 and you choose the event start day as the 20th of that month, then the days AFTER the 25th of that month would be greyed out (not able to be chosen) etc.

Also was wondering if on the event time – can you make it that the end time cannot be before the start time (i.e you cant choose 2pm start and then choose 7 AM finish by mistake (i.e choosing 7am rather than 7pm by mistake)

Somewhat like the date range does in that you cant choose a finish date earlier than the start date as the earlier dates get greyed out (cannot be chosen)

Thanks.
