I've been used to resourcing all aspects of the data I input, and it doesn't seem to be possible to do one or two things...
1) Add a resource to an alternative name, to show where you got it from...
2) Add a resource to an address or a place (e.g., a map), so that you don't have to add that resource (or in fact remember you have one!) to each instance of use of that place/address. In other words, tie the resource to the address, or place, etc., so that it travels with it when you assign it to a person.
Of course, it could be that I'm missing something, which is why I'm posting it here first, as I know you guys will be able to point me in the right direction...
