Acabei de usar um script do PowerShell para fazer isso.
$appReqs = Get-WmiObject -ComputerName <computername> '
-Namespace root/SMS/site_<mysite> '
-Class SMS_UserApplicationRequest '
-Filter "RequestGuid = '<array of GUIDs from previous activity>'"
foreach ($appReq in $appReqs) {
$comment = $appReq.Comments
$user = $appReq.User
$appName = $appReq.Application
$date = $appReq.ConvertToDateTime($appReq.LastModifiedDate)
}
