Icecrown Random Dungeon Finder - Dungeons with requiring keys

Would it be possible to tweak Icerown's RDF algorithm so that it prefers to group people for dungeons that drop prerequisite keys that can then be used LATER in an adjoining or in-series dungeon as the players level up (Dire Maul, Stratholme, etc.)?

An example is Stratholme (55-65). There shouldn't be ANY reason to queue an entire group for the Service Entrance/backdoor compared to the Main Entrance unless at least one person has a key. I've been queued into Stratholme (55-65) Service Entrance at least 7 times on 3 different characters and EACH time no one has the key. And if the entire party wants to troll and NOT kick, we all have to wait for someone to leave first to get the Deserter/RDF debuff.

This isn't like Blackrock Depths where the key is OBTAINABLE within the same RDF group (via dying and getting the quest). Stratholme Main Entrance is impossible to get to in an RDF group that was queued to the Service Entrance.
