LUT shader requests

Longer post in the Troubleshooting section asking how to make this on my own.
But here this is a edit to request these features from some that knows how already. 

Request to create a LUT apply shader that populates a list of textures (PNG images) from a specific folder.
Because manually editing a multi-LUT PNG order in Photoshop is frustrating. Since I got a lot of different size Luts.
But this could pertain to multi lut png's too. 

To automatically populate the texture names from a folder with quotation marks and file extensions
into a preprocessor drop-down.
Then can quickly use Luts from a custom folder.
Example press a name from that pre-processor window
and it applies it to the top name field ( if I have many fields ) automatically figures the size.
If its single lut then all good. If its multi lut, then it should have extra arrows to cycle it.
And a different arrow to cycle texture names in the folder so even being between multi lut png stacks. 
For maximum efficiency.

Or have a list of not just one Lut but multi luts, you can cycle
through different stacks, then cycle through each individual stack.
This should work for multi or single luts.

The qouteations around lut name fields slows the navigation too.
Example "lut.png" if you have custom luts, this can be time consuming manually trying a folder of different luts.

Maybe the new "Add-on" could do this? (I don't know how to make a Add-on).
