You can use Powershell to achive this task Open notepad and write the following script

Add-PSSnapin Microsoft.sharepoint.powershell
$Groups =("Group1","Group2")
foreach($g in $Groups)
{
  Set-SPUser -Identity 'domain\username' -Web http://yoursite -Group $g
}

Now save this script with PS extension then by right click on it you can run this script.
