Shaders - hiding property in inspector

So I have a somewhat unique problem. I have some really awkward shaders that I'm using for a very specific purpose, and one of the things they require is a "dummy texture". Essentially, this is a texture that exists, but doesn't need to be set. The purpose of this is to trick part of Unity's rendering system, so I can use it as a work around to achieve what I need. Now, what I'd really like to do is keep this dummy texture completely under the hood. That is, hide it in the inspector. I noted that some of the terrain shaders had some properties marked with [HideInInspector], but this didn't seem to work. I then had a look at custom material editors. While these will work, I have quite a few different shaders using this, so I'd rather not have to right a custom editor for each one, just to ignore one property. I did wonder if there was a way to exclude the property from the default inspector drawing through a custom editor, since that way I could use the same one for all the shaders, but I couldn't find anything. I also considered dynamically searching through a list of the shader properties, but I don't seem to be able to do this, either. Can anyone help me do this, or is my only solution to write an editor for each shader?
