When you create a template from a bolted connection it does not retain accurate connection parts.
For instance if I select a bolt, washer narrow A, washer narrow A, nylon/insert locknut and save it as a bolt template in the bolted connection window...
On next insertion you get bolt, washer wide B, washer wide B, all metal lock nut
Ther's not a lot of point in having a template if it only retains partial information.
