Is this 4 hours in addition to any hours they may work during their on-call week? If it is, you could always do a paid non-job event that is recurring. When you click anywhere on the dispatch board and click "Edit Event" in the popup you can add more detail to the non-job event you are creating. Here you can name the event, assign dates and times, set up a repeat schedule, assign the timesheet code, provide a description, and add additional members to the event. As long as these are paid events this will also show up in the technician timesheet reports. We do something similar to this for our techs. We aren't open for regular business on Sundays so each Sunday for 3 hours we have an event for whoever the on-call techs are for the week. The downside is the only repeat options are daily, weekly, monthly, and yearly. Our guys are only on call for one week every other month, so right now we just manually change who is assigned to the event each week, which only takes a couple of minutes to do.
