Not to be rude, but what exactly is so awkward or inconvenient that warrants the Developers taking care of this? I don't see why they should have to jump through hoops when you already have the tools to automate it. Are you running out of macro-space? You should ask for more of that then, as it's all stored client-side anyway.
