My company deals with a variety of different customers and each one has there specific machine standards.  When we change from one job to another the designs can be quite similar but the standard components need to change such as bolts.  Hole wizard is good for changing inch holes to metric with drop down menus (time consuming but relatively easy).  Bolts on the other hand are much more frustrating.  I have to delete the imperial bolt and then drag in the metric bolt, then go through the whole process of selecting correct size and lengths.  Does anyone do things differently or is this the way it has to be done?  On that same note, what about changing from a socket head cap screw to a button head cap screw?  Delete and re-insert or is there a better way?

Appreciate any assistance
