Knowing Which Packages Are Nested Where

Apologies if someone's already answered this, but a solid 15 minutes of Googling yielded no results.

Background: I've unofficially become the PDQ master for our company's tiny IT team, and I've been trying to go though and update outdated custom packages and outright replace them when necessary. However, when it is necessary to replace a package (for example keeping the old package going while I test out a new one that works differently), I then need to go find all the other packages it's nested within and switch those to the new version of the package. Otherwise, if I disable/delete the old one, I either have to search for /!\ symbols, or I'm leaving a package crippled without knowing it.

I could work around this by simply nesting the new package inside the old one and disabling all the other steps, but that is neither terribly elegant, nor does it solve the underlying problem if that package itself gets called upon later on.

So what I want to know is this: is there a menu option or hidden tab that will show what other packages in the library have the one I'm looking at nested? An option within a package that says "this package is nested within the following packages: x, y, z." If not, I think it'd make a great feature request.

Thanks in advance!
