I will describe to you what i have in my mind.
Lets say that we have successfully dumped a very very large table via SQL injection.

The Dumped Columns "Users" and "Passwords" look like this:
Total users: 8003

---------------------------------
|     Users     |    Password |
----------------------------------
|     John      |    12345       |
----------------------------------
 [8000 user credentials here]
----------------------------------
|     Nick       |    dragon34  |
----------------------------------
|     David     |    qwerty      |
----------------------------------

Now the User "Nick" changes his password to something else and we want to find the new password, but we don't want to go through all the 8001 users that are above him.

Is there some argument for Sqlmap to dump only this user?
Can we start from user "Nick" and skip all the above?

Thanks in advance.
