Hello All,
I would like to know if it is possible to set up resources and/or working hours so that the business closures are automatically observed by default. As an example, the following shows what I mean (ie, I would like the Observe Business Closures slider to be enabled as default behaviour as it is currently disabled by default):

Our D365 instance has been heavily customised so I am open to the possibility that one/more options have been hidden by developers but since I don't have the ability to look under the hood to see whether it is the case, I would like to ask about the various ways that business closures can be set to be automatically observed by default.
Also, from https://blog.magnetismsolutions.com/blog/12-02-14/Scheduling_Work_Hours_and_Business_Closure_Dynamics_CRM_2011.aspx, the "If we open our Resources that are enabled to observe business closures we will be able to see this holiday appear on their work calendar" sentence picked my interest in that it suggests that it is possible to enable resources to observe business closures by default.
Thank you in advance.
Michael
