Ical Popup reminder question

[grafikat]

I found this question while trying to find the answer to it! Seems I'm not the only one who can't figure it out:

I would like is a way to modify the reminder times. When an event pops up I can only choose: repeat in 1 minute, 5 minutes, 1 hour, sometimes 2 hours... I would like to have something like 10 minutes before event starts or in x hours, where x is freely definable - that would be great

Any thoughts are appreciated!
