As Paul indicates, there is no "Easy" button built into Visio to do this.
As Yacine indicates, most everything is adjustable. By that, either manually, or by code.
If there are only a few shapes, it might be quicker to do it manually.
1.) Drag shape to drawing, grab and move the rotation center to upper left,
or
2.) Open shapesheet, edit the LocPinX = width*0 and LocPinY = height*1. Close shapesheet.
To avoid repeating process every time, save each modified shape to custom stencil. You could even create a template that loads your custom stencil(s) automatically.
If you want to do all shapes on a Visio provided stencil, I'd save the stencil as some custom name, then you need code to run thru each shape and change the LocPinX and LocPinY. Save custom stencil when code completes.
