Yes, I received some info from support. The most relevant parts:
"Currently it is possible to launch Xbench with selected standard QA checks defined in .xml file and the files and checklist to use in a .xbp file, so that you have to just click "Check Ongoing Translation" to open the report in Xbench and interact with the results."
File formats documentation: http://forum.xbench.net/t/apsic-xbench-3-0-file-formats-documented-on-github/221
"It is not possible to obtain directly a .html or .xlsx file with the QA results. You need to export it manually after having interacted with it."
