Expand possible dataset configurations in the training report
Created by: RoyStegeman
This resolves #1707
I'm not really happy about the way it's implemented now. The problem is that the chi2 info in the reports is generated by collecting over the fitcontexts so there's not an easy way to insert a set of preferred datasets in the vp workflow.
I guess it's probably somehow possible to edit the reportengine graph itself? But this seems like it would be a pain. Maybe @Zaharid has an idea?
