Daytime and Night-time Agent Options

In my team, ICM simulations are spread out to run across all of our modelling PCs, via the coordinator. However, we are struggling to reach a compromise in setting the "Max threads total" value for some users - the balance between letting sims complete quickly, vs not slowing down the agent PC for other local tasks (model build, Excel, etc.). One glaring limitation of this setting is that it applies to the PC 24hours a day, 7days a week, until next changed by the user. But we all work regular office hours, so there is no need to limit threads out of office hours. So this request is to implement two boxes for the "Max threads total" setting - one for working hours (say 9am to 5pm), and one for the rest of the time.
