Easy way to open up Orokin Derelict Missions

[Hyohakusha]

There's no way I'm the first person to think of this.

1 - Copy the Fissure mission select tab onto another spot on the mission bar
2 - Replace Fissure types with Derelict mission types. Instead of randomized fissures, just have Derelict exterm/cap/defence etc. Wouldn't even need the randomizer function since they're all set mission types.
3 - Instead of a relic select, it just checks if you have the corresponding key type.
4 - ???
5 - Profit

Only new thing it would need is an icon for the mission bar.

But is the ease of accessing the missions worth the effort? This doesn't seem like a necessary use of the special mission tab.
