How to preserve a value and inject back in later?

Describe the problem/error/question

I am extremely new to all this so I am sorry if this is a stupid question. I am trying to build a RAG system using Qdrant. My Add and Delete paths work great. So for change I figured I could just duplicate and string the 2 processes along BUT my delete process strips out the original path that is passed from the File Change Trigger so by the time it deletes and should trigger the Read/Write node it doesn’t have the path it needs. Is there some form of node I can put in that preserves the original path and runs parallel to the delete process and waits for it to complete and then injects it into the Read/Write? Or some other way to handle it? Thanks!

What is the error message (if any)?

Hey @dping28 , I think what you need is the means described in Output of other nodes | n8n Docs. The data is still available, you just need to know how to access it.
