Consider revisiting your account strategy. Hundreds of accounts is way too many and it's unmanageable. Even a company with tens of thousands of employees couldn't have anywhere near that. Enforce some tags on purpose, team, business unit, dev or prod. It shouldn't be allowed or possible to create instances without any information. Enforce the rules, if an instance has no information it will be shutdown next week and deleted next month. People will take tagging seriously very soon. I've seen businesses who adopted AWS without any strategy and with revolving contractors as employees. A few months later, it's a hundred instances without a single name or tag, each one costing thousands of dollars a month for the more expensive. If the company cares about costs and resources management, it's easy to achieve. If it doesn't care, then doesn't matter, not your money.
