Full dynamic matrix support

Hey,
I’m currently reading the documentation and was wondering if there is a way to have the task matrix fully dynamic.

For example, I have a repository with the folder structure

a
b
c
d

I want to create a task for each folder without specifying them manually inside the config.jsonnet file.

In Github Actions for example I can specify the matrix to be dependent on the output of a previous step.

Has agola a similar feature?
