[phenixbb] chain name lentgh

Hi, We are using phenix version 1.20.1-4487. The protein complex we are processing has more than 100 chains. For this complex we would like to use chain names longer than 2 characters but I see that phenix output truncates the names to the last two characters. Is there any way to avoid this constraint, that is, can we get output files with longer chain names? thanks for the help Roberto
