Embedding existing Sketchup dialogs in new ones

[talig]

Hi everyone,
I want to make a dialog that asks the user for a start date & time of a period, and an end date&time.
I COULD write a nice web dialog for that purpose, but I dislike the notion of "re-inventing" the wheel, and the existing shadow info dialog will always look like a more "native" option for Sketchup.
Is there a way that I could create my own dialog (web or not) that uses two instances of the original shadow info dialog in a nice single window?
Thanks,

• Tali
