How do I map this scenario?

[TaylorWalston]

I have an object with child members who's yaml prefix changes...
CHART-HsycsjVqyp:
object properties
CHART-JbCeaQPIIs:
object properties

I would like to deserialize them to a collection of Chart[], but the object mapper is expecting an explicit named object on my object class that matches the exact chart name, which I can't anticipate. Any ideas or an example I can work from?
