Just like Nick already pointed out in the answer to your new question … it is unclear what you’re talking about.
I already asked in your first thread … you may explain what it ACTUALLY is, what you’re trying to do. The bigger picture … not the way you think you have to go to achieve what you want.
You can insert whatever you want … … if it’s literally $a you can do
$ht = @{
Name = 1
CPU = '$A'
}
But in PowerShell the $ sign represents a variable. So it might be tricky sometimes if you need a literal $A.
