Get a provider from the fx based on a name tag

[UWEMAKAN]

I have an application that processes transactions using different processors based on the value of certain attributes in the incoming request. Currently, I defined an interface called Processor and provided implementations for each processor supported in my application. I then register the constructor of each concrete implementation of my Processor interface with a name tag. I would like to get a specific processor from fx using the name tag in my router logic. To handle this today, I defined a processor factory that receives all the processors in a params struct annotated with fx.In and defines a map of processor name to processor implementation and a getProcessor func that takes the processor name and returns the processor if available.

After writing this, I now think it is probably a bad idea to be able to reach into fx and get a specific dependency at least in my use case because this will make fx part of my business logic and tightly couple my application logic with a specific DI tool.
That being said, is there a cleaner and better way to handle what I described above?
