A token for right most part of GROUP path

The ##GROUP## token provides a command delimited list of the full paths of groups, example:

Business Services/EMEA/Service Z,  Business Services/APAC/Service X

Can you please add another token which provides only the right most part, example:

Service Z,  Service X

We want to send the groups to a webhook, but the full paths are too long and we don't have the option to do any processing at the webhook end.
