Geopak CR - Minimum length Contour to Label

I am currently erasing a lot of of extra index contour labels (the labels are large since it is a large scale drawing) I have lots of small index contours that form small closed loops (The TIN is LiDAR generated, so I have lots of these). Each contour gets a one label no matter what the label spacing is. See Screenshot

An option to have a minimum length to have a contour be labeled would be nice, whether is user inputted, or hard coded to some factor of the label size.

 

TIA
