Adding mixed media in sequence

Hi,

I´ am using version 6.2 (Mac) and like to add pictures and videos in the sequence they were taken. The media browser allows me to either select pictures or video - not both at the same time. When importing pictures and videos in 2 steps either all videos or pictures are in front and not in the sequence they were taken.

When using the Apple Photo app to trag all media files at the same time in FotoMagico the sequence is OK, but the videos are converted to pictures during the import.

Trying the same on the iPad seems to work as I can mark all (mixed media) files in the media browser at the same time.

What do I do wrong on the Mac or where is the trick?
