Donor set recurring start date on a Drupal Webform Contribution Integration
The short answer is:

No.

Unfortunately Webform CiviCRM integration does not currently support selecting the start date for a recurring contribution. 

The longer answer is that it would not be impossible nor incredibly complex to add this field as a supported option for the CiviCRM integration to allow you to expose this option via Webform &amp; CiviCRM.
