HUD Overlay specific fixed position?

I find the HUD Overlay very useful, especially combined with applescript. I would like to make it appear at top center of the screen (over the menubar). But can't seem to find the command to do it (BTTActionHUDPosition only seems to allow 5 preset positions even though when set to "mouse position" it's able to appear at anyplace, as long as the mouse is already there, of course). Am I'm missing something? Thanks!

The HUDs can only be shown at the predefined positions. You could maybe create a floating menu that is positioned above your menu bar and show/hide it depending on your needs
