Lightmap UV Question

Hi everybody, I made a second UV channel for my lightmap UV’s but I can’t find the lightmapcoordinateindex property in UE4 to change it to my second channel, where is it at now?

EDIT: Literally just found it, for future reference for anyone who sees this thread, its in static mesh settings.

Is hidden in Static Mesh Settings. In Static Mesh Editor use Search Bar for this and others searching.
