No, but I could probably add it easily or you could make the modification yourself.
On line 2841 of PAL.ps1, here is the code:
ForEach ($XmlExcludeNode in $XmlDataSource.SelectNodes('./EXCLUDE'))
If ($XmlExcludeNode.INSTANCE -eq $XmlCounterInstanceNode.NAME)
$IsCounterInstanceMatch = $False
You could change the -eq to be a -match for a regular expression. I would need to test it.
What kind of analysis are you trying to create?
