Sorry for the delay.
I checked and it is working. However, you need to enter the symbols using MT symbol format. That means that you need to use either :MI or :BIT suffix. The symbols themselves can be either the alphabetic ones (TAS for example), or the codes, such as IT0000060886. However, the list cannot contain both types of symbols, so you have to use either one type, or the other, but not both
So, a valid symbol as entered into MT, would be:
TAS:MI
or
IT0000060886:MI
Let me know if that works OK for you
