Creating TGA files for each Mesh

When I purchase an asset pack on marketplace I have a need to create a .TGA file from each mesh. Then pack the files and publish it to my game. So my steps go like this.

  1. In my explorer directory I create a .tga file for each mesh

  1. Next I have to open each image, screenshot the icon from unreal and paste it in to the newly created file.

The process of having to create the files is not a big deal but having to copy and paste then resize the image in each TGA file is a total resource hoar. Does anyone know how I can easily get .tga files for each mesh in a pack into my explorer library? Are there any plugins or anything that would allow this in batch process or am I stuck with the above method?

Thanks
