Is your feature request related to a problem? Please describe.
I love how SavedInstances tracks my old expac LFR wing progress in the minimap tooltip, but I often forget to check that and forget which named wing I finished with in a previous farming session.

Describe the solution you'd like
Showing the LFR wing progress in the NPC dialog would make it super quick and easy to tell which LFR wings have been completed.

e.g. (Seer Kazal, WoD LFR)

Grant me a vision of the Imperator's Rise atop Highmaul. [1/1]
Grant me a vision of the Blackrock Foundry's Slagworks. [2/3]
Grant me a vision of the Blackrock Foundary's Black Forge. [0/3]

Describe alternatives you've considered
Displaying this in a tooltip when hovering the dialog option would also provide an easy way to check this info. This could also be a place to display more info, such as the specific bosses killed/skipped, similar to when you hover the full raid progress in the main SavedInstances window.
