I can no longer choose my kbps of the desired format I want when importing/converting from the DESKTOP.
No longer? This was never an option.
Where did you select this previously?
If the file is one iTunes already can use (WAV, AIFF, MP3, AAC or Apple Lossless), it will simply add it to iTunes. It never asked what you wanted to convert it to.
However, it can be done without having to add and and then convert.
Go to iTunes prefs -> General and click th eImport setting button.
Set the format /bitrate you want the imported files to be.
Now hold the Option key and go to menu Advanced -> Convert selection to...
This will call up a windows to select folder/file. Select what you want, then OK.
This will import and convert the files the format you have set in iTunes prefs - Importing.
