tex export format

Would it be possible to add tex as an export format? Nothing complicated, everything similar to the plain text (txt) format apart from a tex extension rather than txt. It would not radically change the world, but it would save me, and other users that write using LaTex rather than MMD, from changing the extension of the exported files from txt to tex. I would be immensely grateful of course.

Context: I am currently writing my PhD thesis (in archaeology) using scrivener and I write using LaTex not MMD. I place all my LaTex markup, including the premable, within the scrivener document as there is quite a lot of this regulating a whole range of things. What I am currently doing when exporting my drafts is to export them as txt files, change the file extensions, and then pick the document up with TexShop to generate the final PDFs.
