Filling an array automatically from contentbrowser in editor?

Hey there,

is there a way to fill an array automatically in the editor? We are working on a movie and need control over switching textures in the sequencer. We have a lot of textures, that have to be filled into those arrays and it would be a ton of work to do it by hand.
I also tried to async load textures, but unfortunately this is not supported in the editor, right?
Any ideas or suggestions?

Thank you in advance for your help and time!

I found a solution myself. I use now a Blutility script for it.
