Adding numbered files

It has been some months since I created a slideshow, so I am a bit rusty.
I have 100 images that are all numbered 001-100. When I add them to FM, they appear in what seems to be a random order. Can I sort them automatically, without having to do it all manually?

In the Manual - Media Browser:

Sorting & Filtering

Click on the sorting icon in the top right corner of the search bar to sort the media files according to certain criteria, e.g. capture date, filename or rating for images, or artist, album, genre for music.
