think I know the answer to this (no?) but is there a way to use values like

today

from https://docs.prefect.io/api/latest/utilities/context.html as parameter defaults? right now I have a separate task that wraps each date param

Hi @Brett Naul - it's not possible to do that as you've outlined, but you can override values in context by passing 

context

 to either 

flow.run

 or in the 

create_flow_run

 GraphQL call. It's possible that we could expose a kwarg on the Parameter class that would draw defaults from context in the future

I guess just subclassing parameter would work; either have

run()

default to today or allow passing a default_factory ?

@Brett Naul yea that sounds like a reasonable approach
