I think you may have misunderstood, so I'll try to clarify.
I'd like to see better loot management options outside of DF parties. Currently, the only way to access these options is to:
a. queue for an instance using the duty finder,
b. be in a full party where the instance has a party requirement, OR be in an undersized party, and
c. enable the option in the DF settings.

The point: it should not be tied to the DF at all, but parties in general.
