Non-linear quasi static analysis with temperature

Hi, I'm following a tutorial of my teacher about a non-linear quasi-static analysis in which there's a temperature gradient. He is using the 2013 version of HM but I have the 2017 one and so I think there is a problem in setting the loadstep. In fact in the loadstep of the 2013 version appears the keyword TEMP in which I can set the load collector for temperature, but in the 2017 version this Keyword misses, so how can I set the temperature load collector in the linear static analysis?
