title: Changing ID type of a member in MailChimp
body: <p>I'm using MailChimp v3.0. </p>
  
  <p>What I want to achieve is to have members of lists been assigned consecutive numbers as theirs IDs.</p>
  
  <p>The question is if it is possible to have a new list's member been assigned <code>id</code> of type <code>int</code> instead of MD5 hash? I'm digging through the documentation and cannot find a single word about lists customization.</p>
  
  <p>If this cannot be done, I have a fall-back of creating custom table where next free <code>id</code> would be stored. Something like sequence object in Oracle databases. The next question is if it is possible to have custom tables.</p>
