Some thoughts for you.
A strength of parametric modeling systems is that drawings update when the model changes. In your case that's a detriment some of the time. You might look into detached drawings as that lets you "lock out" changes. Also consider making a config in the assy that is locked in the desired drawing position. This lets you control what the drawing will use while at the same time allowing the flexible stuff for the models.
Thank You Wayne! The configuration views for the assembly drawings is working out perfectly for us! Thanks again for your help!
