Adjust the times for "add call reminder"

Since version 4.0 (think so) there is a new useful function, the setting of a call reminder from the call history. The reminder times to be selected are 30 min, 1h, 2h and 3h. Is there a way to modify these times? I would like to be able to set 10 min, 15 min, 30 min and 1h.
