How do I change the requester details?

When are we going to be able to decide on what we want in the requester details.
 
Currently - ours shows a field called Job Title - a field we do NOT want. We can't even hide this field.
There are also some additional fields we might like to add to this section but this option is just not available to us.
 
Can you please advise on when or if this is ever going to be available.       
 
Thanks
Eithne
