Trying to add Plotly express to subplots


According to Plotly documentation (Subplots with Python):

Plotly Express does not support arbitrary subplot capabilities, instead it supports faceting by a given data dimension, and it also supports marginal charts to display distribution information.

As such Plotly express is not an option for me.

Is there any way to retrieve trace object(s) from a Plotly Express figure so I can add the traces to a subplot figure?

Thank you
