Calculation Manager variables not showing in snapshot

Summary

Calculation Manager variables cannot be exported via the Migration tool unless a business rule uses them

Hi everyone,

I found some strange behavior with Calculation Manager variables. If you look at your artifact snapshot, or just export all of Calculation Manager via Migration screen, there is no reference to any variables created there. Thus, if you create say 5 Calc Mgr variables, take a backup of all of Calc Mgr, delete those variables, then import the backup, they do not get recreated.

What I did notice was that if you create a variable, then use it in a business rule, it will be part of the snapshot/backup, though it still does not show as a standalone object in the snapshot. Is this intended?
