I'm trying to use the melody sight singing exercise to practice chord progressions singing arpeggios and I'm encountering some problems. Because arpeggios have a very broad span, sometimes a note is outside my vocal range, so i have to sing it an octave lower. The same progression fits differently in my vocal range depending on the key, and entering each progression for every key is very time consuming. I would like to enter it once, and then use the random key feature of earmaster to create the question in any key.
Here is an example, I-V, in C:

When this is in the key of G, transposing all the notes like earmaster does puts some notes outside of my vocal range. This has notes too hight for me:

This has notes too low for me:

This is what a I need to sing:

So being able to sing the notes in any octave is the only way I can save myself the effort of entering the progression fitting my vocal range for every key. Is it possible to add this option to the exercise?
Thanks!
