With the R1 release we will be including a configuration option for just this use, although it will still be defaulted to 'off' and you will need to manually turn it on. Within the project settings XML a new tag will be inserted as follows:
<SynchronizationSettings AutoSyncNewEntities="false" />
Modifying the AutoSyncNewEntities value to "true" will tell TeamPulse to always mark all new entities to be synced on creation.
All the best,
the Telerik team
