Create an Automation rule that allows to assign an issue to an On-Call agent

It would be nice to have an option in the Automation Rules that allows us to assign an issue to an agent who is On-Call, according to the schedule that we can see inboth, JSM and Opsgenie, we have a helpdesk and we have people working 24/7 in 3 diferent schedules, but the Automation rule only allows me to automacally assign the issues to the members of the Service Desk team, but not based in their schedules, it just assign them  according to the balanced workload, but we need to assign them, besides of that, in the agent's schedule
