Hm. Although we have Universal FMS' installed - I can tell you that they have a special "TEMP COMP"-feature that will allow you to enter the destination airport ground temperature. The box then calculates the new altitudes automatically...
Should be the same for every manufacturer/software??? Haven't you been given the chance to practise this in the flight stimulator on your PC/OPCs?
The Smiths FMC offers only ISA DEV/QNH alteration on the DESCENT FORCAST page and I canīt find anything in my documentation concerning approaches.

As long as I donīt know for sure how to modify correctly I am back to V/S and correct it manually during cold weather.
Thanks for the replies
