Export Local Administrators group for remote computers

Using this below code to export the local administrator, it is giving me what I ask for but not format I want. The format I am getting is giving me the all the members in single record; I want each member in a seperate record.

What I am getting -
ComputerName, Members
comp1, member1,member2,member3

What I am trying to get -
ComputerName,Members
comp1,member1
comp1,member2
comp1,member3
comp2,member1
comp2,member2

invoke-command {
    $members = net localgroup administrators |
    where {$_ -AND $_ -notmatch "command completed successfully"} |
    select -skip 4
    New-Object PSObject -Property @{
    Computername = $env:COMPUTERNAME
    Group = "Administrators"
    Members=$members
    }
    } -computer comp1,comp2  -HideComputerName |
    Select ComputerName,Members 

Is there a particular reason why you’re not using PowerShell cmdlets like Get-LocalUser, Get-LocalGroup and Get-LocalGroupMember?
