Can I set up auto number with several different prefixes and different starting number?


I am taking over several existing and upcoming projects and have set up sheets for each project and an overview sheet for all existing projects. I am now at the point where a number of new one are staring and would like to auto-number them however the system that was set up is each type of project has a different starting number e.g house 1000 flat 2000 bungalow 3000 and so on, the issue is we may be up to 3065 in bungalow and 1235 in house - is there an easy way to auto number new projects as they come in?
