I have successfully recreated the bash tags and settings from fallout3's BOSS masterlist using brute force.
Instructions:
-Download fallout3's BOSS masterlist from the BOSS program.
-Open Wrye Bash/Flash whatever it's called ;p
-Find the name of the mod you wish to adjust the tags for and search for it in the Fallout 3 Masterlist.
-Set tags accordingly.
-Rinse and repeat for each mod.
This is somewhat painstaking, but it allows for a full bashed patch with mergeable and deactivatable mods. No crashes and requested records are changed according to tags. In other words this works 100% as far as I can tell.
