Is not possible to add arrays-based fields using Dual Write in Finance and Operations app as Dual Write seems to not be understanding the metadata in the field.

When we try to use a real type extending from AmountMST in the Dataverse, it appears in Dynamics 365 Finance and Operations as string and is not possible to change this behavior.

It should be very interesting to add this functionality to be able to add arrays and containers from Dataverse to Finance.
