2 Format Changes in WTB

For the new WTB, is there a way to:

1) Select MCQ in groups of NOT 10, 20, or 30 questions? I would like to select 24 or 48 (in order to practice actual REG testlets) but all that the new format gives me are 10,20, or 30 options.

2) Change the list format of out how questions are given. It was nice being able to work through MCQ in a similar view like the actual test (i.e. all question numbers listed at the bottom and the screen only shows you one question at a time)?
