Linking specific providers to input flows via Python/IPC server.

Question

I am trying to use the IPC server to build processes based on external data. I have successfully managed to import a process with input/output flows and a quantitative reference, however, I am not able to add a provider (without manually choosing one),

Is there a way to also integrate choosing a provider into my python script? So that I can produce a process with inputs, outputs, as well as chosen providers based on different conditions?

I am using openLCA2.6.1 + VS code

Thanks!
