How to use the presence plugin?

Ok so I am using the presence plug in but I am looking to do a little more with it and I need to know if it is possible. Basically we know we can display things like this:

User

Status

Image

Nathan

Online

(my online status icon)

I really want to be able to do something like this:

User

Status

Last Status

Nathan

Offline

Headed to Client A

Homer

Online

On way to Client B

Brian

Offline

Out at Client C

It looks like when I look at Spark offline users or Adium offline users the last status thing is only “Last seen: Logging off” That doesn’t really help me right now. So how can I use the database or the presence plug in to display this type of information. We would like to start using this information as a type of in/out board.
