Defualt live nesting depth for callout

Hi

When I create a callout (lets say a plan callout for this example) and with it create a drawing and sheet model, the live nesting depth is set to 99 in both models. 

In my Drawingseed_structural.dgnlib the callouts corresponding drawing model have the live nesting depth set to 1 for the design file.

So how do I change the default value if not there?
