Filter based on other field value

Hello experts,

I'm currently analyzing GTP data, and I would like to make a dynamic filter, to find all user plane traffic related to that GTP session.

I've been searching for it, but couldn't find anything.

So, basically the idea is that I create a IP Filter based on the IP contained in the gtp.user_ipv4 field of GTP Create PDP Context Response.

I've tried the following: ip.addr==gtp.user_ipv4

But didn't get any results, so I wonder if there is a way to do it or not. If not, would Wireshark developers consider doing it for future releases?
