How do I link scales of views on new drawing template to the model (automatically)

I have created a template for a model and drawing. The model , and assembly will not change very much in terms of shape. However, the actual size can vary by a factor of 8. I have created a drawing with pre-defined views but I don't want them to blow up because the size of the model changed so drastically. If I could link the scaling to some feature that is representative of the model, say the major diameter, and then push this to the drawing, the basic formatting, dimensioning, and annotation of the drawing views would be preserved.
