Perform only an incoming OR outgoing baseline synchronization on a Link, not both at once

At the moment it doesn't seem to be possible to perform either an incoming or outgoing baseline sync operation on a Link - only both combined, with the order and/or parallelism of execution unspecified.

It would be tremendously helpful during environment deploy and remedial BAU activities if we had the facility to perform each operation independently, rather than having to go through hoops with prescriptive data load regimes or messing around with filters or editing PowerShell Tasks.
