PowerShell code to copy Sql Server Reporting Services report security/permissions from one user to another

Question

I'm new to Powershell. But I need to find out whether it is possible to mimic a user's permissions on different SSRS reports (as some of these users have permissions to hundreds of reports) and grant these permissions to other AD users. I looked online, but haven't been able to find anything that can do that..yet. Was wondering if this is possible at all.
