Are you using a shape master?
If you are using the shapes provided you will need to make a master shape and change the properties to what you desire and save the master. However that only works for some of the properties.
If, for example, you are using a timeline interval and you wish the start and stop time to be picked up from a data base, it wont do it on the drop of the master. This is because when you drop an interval onto a timeline it has autoconfig properties (same with the timeline itself).
The only way I found around that was to set my masters properties to point the desired information and everytime I dropped onto a timeline I went into the Shape Sheet and deleted the auto info forcing it to default to my settings.
A bit of a pain if you have a lot of shapes to deal with but once they are on the timeline the data base controls where they sit on it.
