I have a "standard" script to do this, as it regularly comes up on the forum...
Please read the comments at the head of the script for further info.
/*
Stack N Number of Docs to Layers.jsx
Stephen Marsh
20th August 2021 Version
A generic, skeleton "framework" script to help fast-track development of similar scripts for combining multiple
"sequence" single-layer files to layers.
This script requires input files from a single folder to be alpha/numeric sorting in order to stack in the correct
set quantity.
Example: File-01.jpg File-02.jpg etc, FileA1.tif FileA2.tif etc, File1a.tif File1b.tif etc.
A minimum of 2 or more files per stack is required. The quantity of input files must be evenly divisible by the stack quantity.
A named action set and action can be set on line 137 to "do something" with the stacked layers.
