Optional Features in Analytic App

[rajatjain1]

I have a app which takes in three files to generate three files.

Is there any way to make the third file optional so that I can generate two files only when I don't have the third file available?

I need the optional feature in the app so even if I don't add the third file, the app should run.

In situations like this I like to use multiple check boxes, or a Listbox in the app interface for the user to select each file they would like to output. If there's only three options, 3 check boxes would be easier to build.

To build this, I would place each file input/output in a separate tool container. Each check box could be configured to enable/disable the tool container of the file process it is related to. 

Check out the attached workflow for an example.
