Layered PSD File swap-able without updating every Loader?

Hi!

I have a .psd file with tons of layers, about 60 or so. All the layers goes through some processing inside fusion.

I'm going to need to regularly swap that psd file for another one with the same layer structure. Since I have 60-70 Loaders out there I need to change every single Loader with the new .psd filename which is cumbersome. Another, but less, cumbersome way is to exit Fusion and rename my "new" psd file exactly as the "old". Is there any simpler, proper, way of doing this?

The first thing that came to my mind was instancing, but it doesn't work on Loaders
The second thing was to publish the filename of the "first" loader and connect it to the rest, but that doesn't work on Loaders either.

Any thoughts?

I guess there is nothing build in
Loader/saver names can't use expressions, so you can't link them to one file input.
Only way I see is to use a custom script like that one: viewtopic.php?f=22&t=53746

Thanks! I'll see what I can make of it.

EDIT: It worked exactly as I wanted! This made my week.
