Whenever I've called my concierge (and earlier my private line agent) to apply a TSU, it seems automatic on an eligible paid rate if the standard suite is available, but the concierge needs to contact the hotel and get permission to confirm an available standard suite for an upgrade on an award stay. My most recent datapoint is an award stay in London (the Churchill) in June.
