Can custom Registered Functions be added without modifying PubSubPlus Transformer itself?

The pubsubplus-processor-message-transformer-1.2.2-User-Guide.pdf document outlines how user configured header transforms can be achieved using Spel Expressions.
It also outlines how these Spel Expressions can use Registered Functions (plural) but then lists one function 'isPayloadBytes()' as a built-in function.
My questions:
- is it possible to register new custom functions for use in Spel expressions for header transforms?
- given that pubsubplus transformer is a packaged product, can custom functions be registered in new code external to the transformer and if so, how ?
