Need ability to Sync Gainsight IDs to SFDC Task

Related products: CS Timeline

We're hoping to better track and potentially backfill some records with new data as we sync Timeline Activities and CTA Tasks to SFDC Tasks.  In order to accomplish this, we would need a tighter relationship between the Gainsight record and the SFDC record.  It would be great if we we could push the Gainsight Ids to a custom field on the SFDC task.
Being able to link Gainsight Tasks (CTAs and Timeline Activities) to their related Task record in Salesforce.com is a huge need for us.
