How to create 4000 over ASTC textures asset bundle

Hi,
My project to create an iOS App made with Unity must have over 4000 textures.
A texture is little size, like 300 x 200 pixel.
I want to be able to get these textures as an asset bundle.

How to make ASTC texture asset bundle I know is below:

1. Drop the jpeg file under the Assets folder in my unity project.
2. Change and Apply Inspector of the jpeg as below:
   • Texture Type : Sprite (2D and UI)
   • Override for iOS : check
   • Format : RGB(A) Compressed ASTC 4x4 block (or other ASTC format)
3. - Drop the texture to Addressables group

loop over 4000 ...

This procedure is a manual method, and it is very hard to do over 4000...

Please let me know if there is a more efficient procedure.

 

Select the folder in which all those textures are stored and use the asset bundle dropdown in the inspector to select/create an asset bundle. This way everything in that folder will end up in that bundle.
