Bulk update contacts and accounts from CRM

Bulk update contacts and accounts from CRM

We currently have scripts that import additions and updates to our user database into CRM, which then syncs to Desk. Syncing works great for new records, but not all the data synced properly the first time—all records synced, but not all fields. If we access a record contact or account record in Desk and choose the “update from CRM” action, the missing data gets pulled in. My question, is there a way to trigger this action for all records instead of manually doing it one by one?
