Multiple Currencies in Report

Hi,

I am the new user in SuiteCRM. I have a question about multiple currencies in report.

My CRM is support multiple currencies and the system automatic to convert the currencies to default currency (US Dollar).

However, when I create a closed-won/amount report in opportunity. it will automatic split to different currency and stage.

During all display is in US dollar, can I group it only for sales stage.

Thanks,
