How do I refer to a nested content picker value in a label template with UFM?

I am working within a Collection view where I have picked my document type’s property which is league.

This is a content picker property, so I can successfully do something like:
{umbContentName: value}
value in this context is the value of the content picker and it is rendered with the umbContentName renderer which picks out the name of the picked node.

However, in this case I need to pick the name of a nested property of league, namely “league.team

Instinctively I try:
{umbContentName: value.team}
and
{umbContentName: value.team[0]}

but both of these render nothing at all.

Is it possible to pick out the nested value somehow?
