In Zbooks only one currency can be mapped to one customer. So you will have 2 customers with the same info except the currency. e.g. original customer daryl K - SRD and second customer daryl K usd - USD (foreign currency). 

The problem is that almost all the customers have 2 names, and that is not efficient. 
When creating reports I want to consolidate these 2 customers to present the base currency with total outstanding balance to the original customer.
If there is a way around this issue than it will be helpful. 

NOTE TO ZOHOBOOKS DEV TEAM: create field to map multiple currencies (or at least a secondary currency) to one customer.
