UFM: Use umbContentName in fallback

[bjarnef]

With UFM I can use the following:

{umbValue: headline | fallback:N/A}

{umbContentName: pickerAlias}

https://docs.umbraco.com/umbraco-cms/reference/umbraco-flavored-markdown

But can I combine these?

In a working project I have a heading property on a block, and a reference property having a content node selected.

Something like the following would be useful:

{ umbValue: heading | fallback: umbContentName: reference }
