Sir's reply --
.
You may update regular trains, as you wish.
However, by tomorrow, there will be another tool/link available for each train, called "clone train". You will get a box to enter...
more... any previous Covid-special train number. After that, the Covid train's TT, rake, news, departure days & classes will be directly copied into the given train. This will save some effort.
Thanks.
