I have tried to check this at so many places but the amount of documentation around this seems to be so scattered that I am not getting any data around same,

So I have a Napili template community in which i custom lightning component is present.

Now I have created a custom lightning tab as well to be used in sf1, but now If I go to dropdown for communities, and select the community I can only see standard tabs and nothing custom So is there a way I can add Custom Lightning component tab to Communities in SF1?
