Feature Request: "Incomplete" Dungeon Search Mode

Motivation

Currently, users must manually select individual dungeons and set keystone level ranges to find groups for dungeons they haven't completed at higher levels. This is time-consuming and inefficient when you want to find groups for the next level of all dungeons you've partially completed.

Desired Changes

Add an "Incomplete" checkbox that automatically:

1. Detects the player's highest completed keystone level for each dungeon
2. Calculates the next level needed for each dungeon (+1 from highest completed)
3. Automatically selects dungeons with incomplete levels
4. Populates the search box with the level range (e.g., "14-16") for server-side filtering
5. Sets difficulty to Mythic+ automatically
6. Greys out individual dungeon checkboxes when active to prevent conflicts

This would streamline the process of finding groups for dungeons at the next level you need to complete, eliminating tedious manual selection.
