How moving an all day event that is repeated without moving all ?

Hello,

I started to use ical recently and I like it.

I have just a new problem and would now if there is a solution for that.

The problem is that: I create a new event, set it as all day time and repeated every day. Then if I move one of those new events to drag it on a specific time in my calendar, all the events move even without asking me if I want change only this event or all.

And this is a big problem for me because I would like every night take the event of the next day to put it somewhere in my schedule. But because my schedule change all the time and that I don't want forget the event I would like do that but It doesn't work.

Also, if I change something else on the current selected event, like the duration, ical finally asks me if I want change all events or only this one. But if I click on only this one, then I'm not able to move back all others in All day option, the option being not available anymore.

I hope there is a solution to that because I would like use it that way.

Thank you a lot.
