Hello, quick question about RxKotlin :
I have an api that send me a list of album with their id, from that id i can get all the pictures from it, i'm using retrofit, so i would like to fetch my list of album and from there create a new object or map that contain the album information associated with the list of picture.

fetchAlbums() return a Single&lt;List&lt;album&gt;&gt;
fetchPhotos(album.id) return a single&lt;List&lt;Picture&gt;&gt;

How can i make a result (album, list&lt;Picture&gt;)??

I was going to use flatmap to do that, but apparently not the good solution
