coverage XML export

I can export coverage reports from the soapUI GUI as an XML file (which is called "entries.xml"). I need to be able to do this from the command line/Ant/Maven as well. Currently, the option to create coverage reports (-g option) only adds coverage information to the PDF/html Project Report and it's not easy to extract the coverage data from that report.

I just want to get the coverage XML via the command line/Ant/Maven. Can we get that option added?
