Extend artifact use , not only for build folder

Hello gitlab team. Concider the folowing .gitlab-ci.yml file

stages:
 - build
 - test

compile:
 stage:build
 script:
 - stuff_compiled

test_1:
 stage: test
 script:
 - do_something_1
 artifacts:
  when: on_failure
  name: "$CI_COMMIT_REF_NAME"
  paths:
  - /root/dir

When test_1 is executed , it creates a folder dir inside root. I want to add it to artifacts but , I get an error saying: no matching files. This is caused because the folder is not a part of the project , as is created during the execution of a job.

Proposal

During the execution some of us create a log file , to monitor what is happening (if for example we run simulations). It would be really usefull if we could extract that file without caching everything. So I would propose the use/extention of artifacts to be able to work outside /build folder.
