Yes, this is a small inconvenience. It would be a smaller inconvenience if the dialog appeared right after selecting the files. When I open a 10 or 20-page PDF, I have to wait something like 20 seconds before seeing the dialog, after which it takes an other 20 seconds to complete the import. If the dialog appeared faster, I could do something else while the document loads.
An other alternative would be to add an "Import page range" menu option below "Import document".
