Thank you for the sample.
I guess it's about time i deal with this class of missing functionality..

This issue did not get any activity in the past 30 days and will be closed in 365 days if no update occurs. Please check if the master branch has fixed it and report again or close the issue.

[termlen0]

Just thought I'd check in to see if I can provide any additional data files to help with the effort.
