Node to change compression settings

Hi Folks,
I dont know if this is posssible. Basically I want to change the compression settings through materials.

Below is an example of my question

  1. I have imported an image as Normal map with “TC Normalmap” as compression settings.
  2. Is there a node which changes it to “TC Default” in materials on the fly.

Or is there any other alternative way to achieve the same.
So that I can apply a single texture as normal map and also diffuse map.

Please advise.
