AutoCAD Inventor :: Custom Properties / Model - Changing Order Of Placed Views

Within the drawing title block we have a 'Text' of type 'Custom Properties - Model' which pulls in a custom iprop from a model which is the models finished weight. This is a common way of auto populating title box entries.

The problem is that the sheet populates the text with the info related to the first viewport placed upon the drawing.

Whilst fine when planned for properly, I quite often encounter upon large multisheet detail drawings, that a user when detailing an IAM, will have forgotten to put the IAM view down first, especially later in the drawing series where the IAM is not required and the user is detailing IPT's.

What I am looking for is a way to change which viewport the border properties are related to ideally, so that if a user has forgotten to place the IAM but has placed 20 IPT's down, I could place an IAM outside of the maximum area, as the 21st object but fool Inventor into thinking this was the first viewport placed down, thus populating the border info correctly.

I don't know of a way to do this currently, either with current Inventor functionality, or by programmatic approach - our current fix is to have the user create another drawing sheet, place the IAM outside the maximum area, copy all his IPT viewports across from the first sheet, then delete the first sheet. Is it possible to change the object order of placed viewports with less disruption?
