[Feature Request] Allow for Optional Input Data #91
Description
Feature Request
Is your feature request related to a problem? Please describe.
There are some use-cases where we might want users to be able to run an analysis on default data or upload their own, allowing for optional data upload might provide a solution to this.
Describe the solution you'd like
Instead of a binary true/false, add a third option for optional for require_upload_data.
Describe alternatives you've considered
The current workaround is to require upload data and then provide a parameter that allows users to specify the upload data filename/select if they want to use default data. However, users still need to upload data even if the model doesn't use it which is a waste of time transferring unnecessary data.
