I want to compare a portfolio that I create with other mutual funds and ETFs using Advanced Chart. I want to be able to pick my portfolio from the list of Comparisons in Advanced Chart.

Yahoo currently offers a simple version of this in the Holdings Summary box at the top of individual portfolio pages. (You can see a screenshot of this at this Dropbox link: https://www.dropbox.com/scl/fi/c3b1d89cz11ejulubz60r/Yahoo-Support-Screenshot.png?rlkey=me8qh2zh06i9ia9kjv0dl1mnw&dl=0)

This should be available in Advanced Chart as well.
