Looked around the app and this feature seems to have been removed with the Renegades update, unless I'm just missing it somehow. Couldn't seem to find anyone asking about this either, other than one thread in the Companion section from 2 days ago with no replies. This was like the one practical use of the app to pick up transmog bounties without having to load into the tower, so I hope I'm just missing it or they plan to reimplement it in future.
