Here is a function a lot of people have said about on forums/comments, which I think might work.
A character export/import.
Basically, the Save Editor can export the characters gear, appearance, xp, level and attributes. Then you can load up another save, lets say, your friends or a NG+, then you select 'Import', which imports those attributes into the other save.
For reasons, might be best to keep quest tags alone.
