We have a deployment job that has a VERSION parameter, which can be a branch name.

Example:
Schedule a job for tomorrow with VERSION=develop.

Schedule a job for next week with VERSION=master.

Scenario 1)

Directly deploy with VERSION=feature/new-buttons

Outcome: The two scheduled jobs still exist.

Scenario 2)

Directly deploy with VERSION=master

Outcome: The scheduled job with VERSION=master doesn't exist anymore.

The outcome in scenario 2 may seem logical. But on the other hand, it's not. If I plan a deployment for next week, I should not have impact when I deploy something right now.

The use case is:

Schedule a certain branch to deploy next week, while in the mean time patches in that branch can be deployed.
