Top to Bottom or Left to Right should be selectable when importing not something that needs to be pre chosen before initiating the Import Audio command.
Being able to do both when importing large lists of audio would be fabulous, ie:
files 1, 2, and 3 Left to Right on a new track
4 -9 Top to Bottom on new tracks
10 - 15 Left to Right on a new track
16 - 19 Left to Right on a new track
20-30 Top to Bottom on new tracks
