How to apply BumpOffset to a texture sample already taking a TexCoord?

Please see screenshot to see what I am trying to do in the editor.

I’ve taken half of the texture via TexCoord, and I am trying to find a way to apply bump offset to it. I am not sure how this could be done, as I’ve already used up the UV slot. Ideally I’d imagine there is a node that would take a TextureSample and allow another UV set to be applied to it.

How can this be done?
