[p4] customization of changeset number

[Kilaru Sambaiah]

Hi All,
  I am new to perforce and it is my first post. I am wondering, whether it
is possible to customize the changeset
  number?

  We are using teamtrack for long time and teamtrack id is something like
000024689, we are planning to migrate
  SCM to perforce.
  My question is upon submit, perforce gives changeset number like 15 or 16,
but my teamtrack id is what I wanted
  to be changeset number. Is it possible to customize?

thanks and regards,
Sam
