Foundation REST contributor/license question

Hello!

We use the API com.ibm.team.repository.common.internal.IContributorRestService/contributor to create a new contributor (i.e. body contains newContributor=true and other information about the contributor).  Are the default access licenses ( https://www.ibm.com/support/knowledgecenter/en/SSYMRC_6.0.0/com.ibm.jazz.repository.web.admin.doc/topics/tmanagedefaultlicense.html ) applied to the new contributor?
If not, is there anyway to apply the default licenses programmatically for a new contributor or do they have to be manually specified with a subsequent call to com.ibm.team.repository.service.internal.ILicenseAdminRestService/assignLicense?

Background:
To avoid interruptions in service/delay, we use a service that propagates new accounts to jazz servers before a daily scheduled sync is done with an external user service. We do this by creating a contributor and then assigning it licenses using the APIs above. Since it does not seem like the default client access licenses are applied to the newly created contributor, I was wondering if there was a way to apply the default access control licenses specified in the JTS without having to specify them manually using assignLicense.

Thanks!
