function Invoke-CCMClientAction {
    <#
        .SYNOPSIS
            Invokes MEMCM Client actions on local or remote machines
        .DESCRIPTION
            This script will allow you to invoke a set of MEMCM Client actions on a machine, providing a list of the actions
        .PARAMETER Schedule
            Define the schedules to run on the machine - 'HardwareInv', 'FullHardwareInv', 'SoftwareInv', 'UpdateScan', 'UpdateEval', 'MachinePol', 'AppEval', 'DDR', 'SourceUpdateMessage', 'SendUnsentStateMessage'
        .PARAMETER CimSession
            Provides CimSessions to invoke actions on
        .PARAMETER ComputerName
            Provides computer names to invoke actions on
        .PARAMETER PSSession
            Provides PSSession to invoke actions on
        .PARAMETER ConnectionPreference
            Determines if the 'Get-CCMConnection' function should check for a PSSession, or a CIMSession first when a ComputerName
            is passed to the function. This is ultimately going to result in the function running faster. The typical use case is
            when you are using the pipeline. In the pipeline scenario, the 'ComputerName' parameter is what is passed along the
            pipeline. The 'Get-CCMConnection' function is used to find the available connections, falling back from the preference
            specified in this parameter, to the the alternative (eg. you specify, PSSession, it falls back to CIMSession), and then
            falling back to ComputerName. Keep in mind that the 'ConnectionPreference' also determines what type of connection / command
            the ComputerName parameter is passed to.
        .EXAMPLE
            C:\PS> Invoke-CCMClientAction -Schedule MachinePol,HardwareInv
                Start a machine policy eval and a hardware inventory cycle
