Is there a way to alert when there's modified content like in InDesign?

I'm using Photoshop 2021 and perhaps this was added into a newer version of Photoshop so I apologize, in advance, if that's the case but I do not believe that to be the case.

 

Photoshop gives you an alert when it "cannot locate linked assets" but doesn't alert you when there are modified linked assets. I know that it adds a warning icon on the layer but it would be far more helpful to warn after opening a document and give a list of all the layers that were modified as well. InDesign warns you when there are modified files, so it doesn't make sense that Photoshop wouldn't. Am I missing something? Is it a preference that I'm unaware of? Is there a script I can use? Is it in a newer version?

In InDesing and Illustrator, linked files are embedded at the document level. In Photoshop, the nesting system is much more complicated - we can create a smart object inside which there will be a linked file, inside this linked file there will be another smart object with linked files inside, and so on. That is, linked objects in Photoshop are rather not part of the document, but part of the layer.

Both InDesign and Illustrator have a Links panel. Photoshop does not and has nothing equivalent.

* using the File -> Scripts -> Script event manager you can add this script to the "open document" event (and it will check the content every time any document is opened)

@jazz-y This is exactly what I was looking for. Thank you so much. I've implemented it and it works perfectly.

I really only wanted it to warn about the first level modified linked layers anyway, while it would be nice for it to warn about the nested ones, it's not at all necessary for my purposes and your explanation makes a lot of sense, thanks again!
