I'm writing a report which will have a number of references such as



ref. 1 - Document A
ref. 2 - Document B
ref. 3 - Document C

But it's quite likely that the order will change or new references will be inserted after it's been written.

So now it might look like;

ref.1 - Document A
ref.2 - Document D
ref.3 - Document B
ref.4 - Document C

Is there a way to make the ref.x a field and then reference it throughout the report so then when I insert a new reference and change the numbering, it all updates automatic.

A but how the caption and cross reference works for tables and figures.

Thanks!
