I don't think so, but correct me if I'm wrong.

If you use this command, you can at least see which flags are set.
$ tshark -r test.cap -T fields -e frame.number -e frame.time -e ip.src 
-e ip.dst -e ip.proto -e tcp.srcport -e tcp.dstport -e frame.len -e tcp.len

-e tcp.flags.cwr -e tcp.flags.ecn -e tcp.flags.urg -e tcp.flags.ack -e tcp.flags.push
-e tcp.flags.reset -e tcp.flags.syn -E header=y > test.csv

Hope this helps somehow
