Mirage Deadeye not showing seprate skill gem window

If you use Mirage Spirit gem it has a separate window for skill that is used by it where you can see all the advanced details and even there you can select weapon set 1 or 2, i was hoping that Mirage Deadeye should have the same advanced info about the skill gem it is using. And please make it work so we can have spirit gems active on both weapon sets but the skill gem used should be able to have separate weapon sets.
