Is it possible to do the following things like 1 or 2 using standard functions or plug-ins?
Note that "output" is not "integrate and export images" but "save as".
The tool I'm using is the Windows version of CLIP STUDIP PAINT PRO (1.10.6).

Thing you want to do
1. I want to "automatically" combine layers in "a certain unit" (ideally the folder unit with the deepest hierarchy) when outputting psb.
・ Details
I want to keep the "layer for contour line" and "layer for coloring" as separate layers when creating an illustration (.clip), and combine them when outputting (.psb).
For example, if you combine layers, you can do it manually, but there are multiple "line layers" and "color layers", and you don't want to do the same work every time you modify and output again. If you make a mistake in the procedure, layers will be irreversibly integrated, and manual operation is risky.

2. I want a layer (also called an output layer) that keeps the drawn contents integrated in real time while having a "contour line layer" and a "coloring layer" respectively.
・ Details
An image in which the line layer and the color layer are used as work layers, and an output layer that refers to them is created separately. I want to hide the working layer at the time of output and not include it in the psb file, but include only the output layer. The output layer is not affected by the display / non-display of the work layer, and always reflects what is displayed.
For example, if you integrate the duplicated layers, you can create it manually, but doing the same work every time you make a correction is expected to have "time cost", "risk of irreversible integration mistake", and "risk of omission of change reflection". So I want to do it automatically.

Reason
CLIP STUDIP PAINT is used to create game materials.
The game is created with a game engine called Unity, and if you import it using "PSD Importer" (the import target is psb format), it will be automatically divided into layers and turned into resources.
The point is this "in layer units", and if you create a "line layer" and a "color layer" separately, each will be a separate resource.
However, when using it in a game, it is inconvenient if they do not have the same resources to create animations.
So I asked Clip Studio if it could be integrated automatically.

I have uploaded the image, but since the ones that are separated by "line" and "color" are treated as separate resources, I want to somehow integrate the "line and color" into one layer. It's a feeling.

It would be helpful if you could tell me if there is a solution other than what you want to do 1 and 2 above.

that's all.
Thank you.
