tshark statistics(-z) output with “ssl” filter(-R/-Y)

As I mentioned in title I want to filter tshark's dests,tree statistics output to show only encrypted(ssl) traffic.

I tried tshark -a duration:30 -Y "ssl" -z dests,tree > output.txt but that doesn't work as I expected. But from wireshark(gui) Statistics > IP Destinations filter:ssl works just fine.

Are there any ways to do this with tshark or should I consider other tools?

Background: I'm writing a java application to automatically fetch scheduled tshark command output to show traffic bandwidth and incoming packets by ports per IP. I am absolutely not an expert in this job. If I'm looking for something wrong to do my job you should feel free to offer me better ways.
