How to bring a specific tab page to the front of the tab page list

Hi, There,

When a tab page list contains multiple tab pages, after the dialogue box is displayed, the first tab page shown in the list will be the the first one listed in the .r file. How can I set a different tab page to be shown first after the dialogue box is openned. I searched all mdlDialog_tabxxx functions and could not found the suitable one.

Any suggestions will be greatly appreciated.
