Reusable Function Libraries for Power BI Dataflows

Is it possible to create a utility dataflow to define all reusable functions and reference that utility in any dataflow that requires them? Similar to how scripting works in JavaScript or Python.

Currently, the only alternative is to rewrite the same function separately in each dataflow, since there is no way to define it once and reuse it across dataflows. This makes the process extremely cumbersome and inefficient, as the functions have to be manually duplicated every time.
