BB Software :: Calendar Software Upgrade Option?

I currently have the Blackberry 9700. I would like to see an option added under the calendar feature. With this phone you can have more them one calendar, which is great. You can set your default calendar; however when you go to add a new entry you can select one of the other calendars. The feature I would like to see is having the option to move an entry from one calendar to another. As it stands now, if I enter an appointment on one calendar, but need to switch it to another calendare, I have to make a new entry and select the other calendar. What I would like to see is when you open the entry to make changes (ie: time, date, location, etc.), you have to the option to move the appointment to a different calendar. So maybe in the next software upgrade an application can be written for this calendar feature.
