Approval Limit for multiple currencies

Summary:

When we configure Approval Limits for Adjustment in the Currency list of value there is the possibility to select the "**** - No Currency". But if we create the adjustment it get the status "Pending Approval" as the configuration was not done.

What is the purpose of this value "**** - No Currency"?

Our customer manage invoices in different currencies? Should we create multiple records for all the users and for all the currencies?

Is there a way to import the approval limits massively?
