I am struggling to figure out how to -- or if it's even possible to -- create a DX scratch org with the "Field Service Lightning" (FSL) feature installed. Based on the feature list here I'm guessing the answer is no and I'll just have to wait. But I'm not sure I'm interpreting that source correctly or missing something entirely since I'm just wrapping my head around DX.
Background: we have a production org with FSL installed and active, along with it's accompanying managed packages. I can create sandboxes from it and do development using standard Metadata API tools, but I was hoping to start a new project using DX. But I'm stuck configuring a scratch org with the proper features.
