Is there an available powershell command for handling security roles?

Here is a sample security roles:

Security Role: Sample Standard User
Entity: Contact
Privilege: Read, Append, and Append To

Security Role: Sample Advance User
Entity: Contact
Privilege: Create, Read, Write, Append, and Append to

Security Role: Sample Admin User
Entity: Contact
Privilege: Create, Read, Write, Delete, Append, and Append to

Configuration for security roles in microsoft dynamics is tedious right?
Using this example, the goal is to replicate a specific security role then apply additional privileges.

Now using the example given above, if we can replicate “Sample Standard User” using powershell to create “Sample Advance User” then add “Create and Read” privilege (again using powershell), we can skip the tedious part of the configuration and create a them programmatically instead.
