Can wireshark distinguish Hol(head of line) blocking section?

I'm studying Wireshark as my degree's project lab. I'd like to distinguish HOL(head of line) Blocking section among captured packets by coloring those packets. I'm wondering if there exists a function like this. If so, I'd appreciate if you tell me how to apply the function. If there isn't one like this, I'd like to create the function and know which source code and where to add new codes. It would be the best if i can do this by putting some lines of code but if not, I'm willing to create a kind of new dissector. I'm hoping someone could help me with this.
