Can we have another sub Service Calendar possible in CRM 2016 Dynamics 365?

Hi Everyone,

We are trying to have another a sub calendar or separately to schedule sub contractors ? which should like service calendar & its functionality?

Isn't possible to do so?

Note - there is no access to service calendar entity also and why?

Current version - CRM 2016 Dynamics 365 8.2+

On- premise

I'm looking forward for another possible solutions also?

Thank you
