Update Pantheon with latest security patch

Hi,  could you push the latest CiviCRM Drupal 7 updates to Pantheon?  I could help out with this in the future, if you could provide some guidance on how to do it.  I was able to update CiviCRM from 4.4 to 4.5 on Pantheon, but they will not allow me to upgrade Drupal Core from 7.26 to 7.31.  The reason being, it's part of the CiviCRM Drupal distribution and all updates to pantheon for Drupal core must be initiated by the distribution's developer.  I guess that's you.   Would you mind pushing the latest CiviCRM Drupal 7 updates to Pantheon, or instructing me on how to accomplish this on your behalf?
Kind regards
