import multiple libraries at a time/no preview

ALlow selection of multiple .zip icon files for import all at one time. You could eotjer
1 provide no preview but OK all
or
2 preview each icon group all on one page or consecutively with the standard ok button for each. This mode would also allow a OK ALL button at the top, removing the necessity of OK-ing each library one by one
or
3 flash each library preview with the standard OK button so that all one has to do is keep clicking OK as each preview is presented.

I like option 2
