AutoCAD Dynamic Blocks :: Editing Fields / Creating New Field Categories

I'm working in AutoCAD 2010 and I would like to make the process of creating 2D documentation easier and faster for myself and my collegues, but during the process I've hit a dead end.

I would like to use fiedds (or something simillar) to partly automate the creation of 2D documentation. We have sheets organized in a specific way and I would like to create a custom field for each of the categories (eg. drawing number, number of parts, designer...) that could be edited easily like the parameters or object properties can. Basically what I would like to do is create custom fields or some other object that can be edited from a list in AutoCAD and then automatically refreshed in text boxes. Is there a possibility to do something like that using fields or perhaps a different solution?
