As with everything in IT, having things standardized generally makes your life easier. Unfortunately in many environments, snapshots tend to get overlooked and their naming convention can end up a little adhoc which can lead to confusion around who and why they were taken.
Ive put together the following script which takes a snapshot with certain key information included e.g

Snapshot Name = CurrentUser TicketNumber Date
Tony 101010 01/06/2019

While you can get the date by clicking on the snapshot, i felt it would make it easier to find the one you require on VMs with several snapshots taken.

Function Name – VPF-TakeSnapshot

<code>Function VPF-TakeSnapshot
{
$CU = $global:DefaultVIServer.User
$VM = Read-Host " Please enter a VM name"
write-host
get-vm $vm | select Name, notes 
write-host
$CorrectVM = Read-Host " Is this the correct VM? (Y/N)"
IF ($CorrectVM -eq "Y" {
	clear
	$Ticket = Read-Host " Please enter a Ticket Number"
	$Description = Read-Host " Please enter a snapshot Description"
	New-Snapshot -VM $VM -Name "$CU - $Ticket - $(get-date -f yyyy-MM-dd)" -Description "$Description"
		Write-Host -NoNewLine " Snapshot Complete, Press any key to continue...";
		$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');
	}
Else {
		$VMs = get-vm $VM
		Write-Host
		Write-Host " ================ Select VM ================"  -ForegroundColor green
		Write-Host
		$i = 1
		$VMs | ForEach-Object -Process {
		Write-Host " $i $($_.Name)  $($_.Notes) "
		$i++
	}
		Write-Host
		Write-Host
		$selection = Read-Host " Please make a selection (Q to Quit)"

	if($selection -eq 'Q'){
		 clear
         Exit
}
	else{
    $VMChoice = $VMs&#91;$selection -1].Name
	$Ticket = Read-Host " Please enter a Ticket Number"
	$Description = Read-Host " Please enter a snapshot Description"
	New-Snapshot -VM $VM -Name "$CU - $Ticket - $(get-date -f yyyy-MM-dd)" -Description "$Description"
		Write-Host -NoNewLine " Snapshot Complete, Press any key to continue...";
		$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');
	}
 }
