setWorkTime per task

Is it possible yet to have custom working time per task, or per resource, with a specific set of dates, instead of either global or 7 days a week.

I.e. for a specific resource, or a specific task, can I set a custom set of dates that are available for work and others not?

Hi @Dominic_Glenn,
It is possible to bind custom calendar, to the task property, like in the following snippet:

You can create as many calendars you want, and bind them to the custom task properties, like "calendar_id": "twoDaysWeek"
API for task/resource/project calendars:

Important: project/resource calendars are available only in the PRO version, you can read more about them in the link at the link above.

Does it help you to solve the problem?
