Getting Full Stack Traces for All Queries in Arize Phoenix

Hello there, I am using Arize Phoenix with Llama Index like so

import phoenix as px
    px.launch_app()
    from llama_index.core import set_global_handler
    set_global_handler("arize_phoenix")
    px.active_session().view()

I am running queries in a loop and I notice I tend to only get the trace of the last query only. Is there anyway to fix it so I get the stack traces of all the queries in that looop?
