Edit to Amplify shader graph in Unity

We have a shader that projects a satellite image over a terrain, we need to add a node/property to the shader that allows us to rotate the image. Attached are images of the amplify graph, 1 close up of the satellite image projection logic and 1 of the whole graph to give you an idea of the work involved. No silly bids please I know this isn't much work and probably can be done in 10-20mins We have a Unity test project all setup, so will just be a case of editing the shader graph and a quick test.
