Using Atlantis with subdirectories without atlantis.yaml (no repo side config)

[adrianbanciu]

Hello, this is for context:
From what I could gather there is no support for the case in which you modify something in the subdirectory and the parent directory runs terragrunt plan/apply.
Example:

project
├── data
│   ├── more_parameters.yaml
│   └── parameters.yaml
└── terragrunt.hcl

The pull request modified something only in project/data/parameters.yaml. Atlantis will try to autoplan in the data subdirectory if autoplan is set detect changes in the parameters.yaml file. The situation is pretty much identical to: #2603

Due to this I'm trying to create my custom solution, which means modifying the TERRAGRUNT_WORKING_DIR environment variable (I know it's not ideal) to project. This seems to function alright, but the commit message falsely indicates that the plan has been ran in the project/data subdirectory.

Could I modify this output through the workflow, without having to overwrite the templates?
And ideally, is there is a way to address subdirectories that's more elegant on the server side, please let me know. 😅
Additionally (a bit beyond of the scope of the initial question), can you make it so when you make a change to parameters.yaml and terragrunt.hcl both, the former is not taken into account, but if you change only parameters.yaml it is?
