When trying to view files in the document History, it appears the filetypes are not associated with the appropriate application. I see how to fix it, either by Group or User:

In the Admin tool:
1) Right-Click on the Group or User
2) Go to Settings
3) Select Viewers and configure

Question: Is there a faster way to do this globally for all filetypes; and not have to do the same settings for each group? Much thanks!
