AutoCAD Inventor :: Import And Use Drawing Standards?

I'm working on homogonizing all of our various templates, making all the new features from newer templates available in the older templates but I'm getting high centered on a step.

I've exported all of the different drawing standards and imported them all into each template which makes all of the upgraded dim styles available in all of the templates. The issue arrises when I save and close then reopen the template the imported standards are missing. It appears that under Manage, Styles Editor, if the standard is not in use it is not saved with the template. If this is the case how do I put them all "in use"? Even if I activate one of the imported standards, save, close, reopen, then activate a different standard and repeat, the imported standard is deleted.
