I think that auto scaling is made only when you insert part first time in to drawing.
You can break view and dimension break lines to get same view size independent on part dimensions. But this will hide middle part of model.
Someone may be able to write a macro to do that, but that would be the only way. Without that you will need to manually adjust your view scale, or the sheet scale if that's what the view is set to.
Thanks for your replies. I am not capable to write a macro in these times. Maybe later
