Is there any way to directly access the IR node when having the corresponding annotated target?

[Wonicon]

Hello, everyone. I am learning FIRRTL pass and Chisel annotation. I want to use annotation to locate the module I want to modify, but as the tutorial[1] shows, I will get a XXXTarget object when consuming annotations. This type of objects mainly contains String fields to indicate which FIRRTL node it is, but does not have a field to point to that node object. Besides brute-force searching, is there any way to elegantly access these node objects?

I have read the following tutorials:
[1] https://www.chisel-lang.org/chisel3/docs/explanations/annotations.html
[2] https://github.com/chipsalliance/firrtl/tree/master/src/main/scala/tutorial
