Hard block (error message) for Limit SC with Asset account assignment

Hi Experts

As per the requirement Limit SC should never have Asset account assignment.

So we need to have a Hard block (error message) for Limit SC with Asset account assignment.

i.e. when we create a Limit SC with Asset account assignment, system should through a Hard Block (error message).

Can anybody please help to set this Hard Block (error message).

Note: In standard, we can create Limit SC with account assignment
