when creating item as structure type "Option/Model" , system is throwing out error

Summary:

I have set all default values at template level for item creation. I have set structure type "option/Model" at different template level for SIK and FG respectively . Also set internal transferrable "NO". But when creating an item , it is reverting internal transferrable "yes" automatically and throwing an error to change structure type as "standard" if internal transferrable is Yes.

But user requirement is to set structure type "option/Model" and internal transferrable is Yes.

Please suggest on this how to resolve . Because manually setting internal transfer to "No" is not acceptable everytime by user.
