Adding the possibility to schedule workflows with public API's

Description of the feature request

Hi, i just noticed that there are no available public API’s for scheduling/rescheduling a build. Is there any plans to add this in the future? I was expecting to see a parameter or something in the current build request:
But there are none and I don’t see any other publicly available requests on the list that we could use for this.
Thank you very much!

Use case / for what or how I would use it

Creating internal utilities such as a chat bot which would schedule builds on demand.
