Limit / tailor tshark conversations output

Hi I have to analyze a large number of pcap files and made a little script that outputs the conversations for tcp and udp.

-q -z conv,tcp -z conv,udp

Thus far everything works fine. The problem is that I only need the top 10-20 entries of total bytes and don't need the last ~60000 entries.

Is there an output filter that can limit the entries to top 10? Or maybe a way to only print the entry if the total traffic (or frames) is greater than a specified value?

Thanks in advance
