How do I set default date format for milestone shapes?

[tfrase]

Hi,

I have Sharepoint task date linked to a Visio timeline. But I have not figured out a way to show FINISH as the date instead of START, or how to always have the date formatted as {M/d}.

For the date, I tried setting =SETATREF(Prop._VisDM_Finish) in Prop.visMilestoneDate but it doesn't seem to work when I connect a new data row to it. It will not update Finish date or move the milestone.

For the date formatting, I see the User.visMask in the shapesheet, but I don't know how I can make the formatting "stick" so I can make a new master shape. I get tired of having to manually set the format every time I drag a new milestone marker. Visio always defaults to "December" for instance, instead of 12/15 - and I can't figure this out. I know it's gotta be simple, though.

Please help!
