How to retrieve more than 1 annotation to CSV

Question

I'm trying to create a report using Get-annotations to retrieve some custom values and actually it works fine, but I only can insert 1 value on report on same line, here below is what I do for 1 value only, is there some syntax to use not like this Get-Annotation -Name value1, value2, value3

$AW= foreach ($vmsowner in $VMsOwners)
{
    $VMlisted = $vmsowner.objectname
    get-vm $VMlisted | Get-Annotation -Name  "Application Owner"| select @{label="VM";expression={$_.AnnotatedEntity}}, @{label="Application Owner";expression={$_.Value}}
}
$AW | ConvertTo-Csv -NoTypeInformation | Out-File  -FilePath $FilenameOwners

Call Get-Annotation inside the calculated property expression(s):

Get-VM |Select @{Name='VM';Expression={$_}},@{Name='Application Owner';Expression={($_ |Get-Annotation -Name 'Application Owner').Value}},,@{Name='Some other tag';Expression={($_ |Get-Annotation -Name 'Some other tag').Value}}

It might quickly become unreadable with all those calculated property definitions, but you could generate them from a list of annotation names:

# define annotations your want to retrieve per vm
$annotations = 'Application Owner', 'Data Owner', 'Some other tag', 'Something else completely'

# generate calculated property definitions
$properties = @(
    @{Name='VM';Expression={$_}}
    $annotations |ForEach-Object {
        $annotationName = $_
        @{Name=$_;Expression=[scriptblock]::Create("`$(`$_ | Get-Annotation -Name '$_').Value")}
    }
)

# fetch VMs and select properties
Get-VM |Select $properties
