Task template referencing roles in another repository?

[ccrembil]

My playbooks are structured in the following way,

• Ansible roles are located in a git project (named L), and
• Ansible playbooks located at specific projects (A, B, C, D), reference the roles defined at project L

At my current server (with no Semaphore yet)

• I clone the role's project L in the role's pathdir
• a playbook (for example at project A) finds the roles at the role's pathdir

I didn't find how to load 2 repositories in Ansible Semaphore.
How do you handle this user case?
