I don't think so there is a built-in platform support for this.
However with some coding you can create a strategy that does the same (put a countdown on the chart).
If you need help with that, I suggest to create a separate topic in the Automated Trading->KnowledgeBase section (as this has nothing to do with Trading Platforms' Bug Reports), and start coding

.
Some help as start:
You will need
a scheduler:

IBar currentBar = history.getBar(chart.getInstrument(), chart.getSelectedPeriod(), OfferSide.BID, 0);
SimpleDateFormat countDownTime = new SimpleDateFormat("HH:mm:ss");
countDownTime.setTimeZone(TimeZone.getTimeZone("GMT"));
String timeLeft = countDownTime.format(currentBar.getTime() + chart.getSelectedPeriod().getInterval() - new Date().getTime()); // put this on the chart
