The needs: Be able to tag machine so ansible playbook can behave accordingly

What I tried:
- input in provisionning template (only fact and variable) but I don't see how fact can be populated and variable are already accessible so no result
- input in webhook with choice but I don't see where I can enter value so webhook crash (no value provided)
- input in job template (for the first run ansible playbook) -> I don't see any popup

I can help with implementation with guidance which file might be useful.
