Is it possible to shorten the Ikea Faktum sliding door wall cabinet?

Hello,

does anyone perhaps know if it is possible to cut the width of the Faktum sliding door wall cabinet? Unfortunately, I cannot go to an Ikea store because it is too far away. I am not concerned about the corpus itself, that would not be a problem. But the rail in which the sliding doors run is not shown in detail online. Maybe there is a (hobby) craftsman here who can say something about it. Many thanks in advance!

You can change everything as you wish, but you should then consider whether it still makes sense...
