Service order with multiple currency in components

Hello SAP Guru.

In SAP, we create service orders (IW31). Sometime we add many components. When the order is completed, we create a quotation (DP80).

Our company currency and G/L account currency is only CHF:

My problem: I create an service order with multiple currency in components (CHF + EUR).

In cost overview tab, only CHF is taken:

If I create a quotation with DP80, only the CHF component is taken. Why the EUR component is not taken?

It's possible to customising the system to it work? Or is only possible with a USER-EXIT?

What the best practice?

Thanks and regards.
