Hi,

I have a workflow that requires a large number of files that happen to
come in pair but are processed by different tools.  One tool allows
the user to specify inputs 1...N and produce a single output.  The
other tool takes a single input and produces a single output.  In the
simplest example say we have two pairs, the workflow looks something
like:

Set1.TypeA \ TypeA.Output
Set2.TypeA /

Set1.TypeB - Set1.TypeB.Output
Set2.TypeB - Set2.TypeB.Output

However when the user runs the workflow the inputs are requested in
random order.  While the inputs are labelled this can be confusing.
It would be nice to be able to order the inputs for the workflow to
always be something like:

Set1.TypeA
Set1.TypeB
Set2.TypeA
Set2.TypeB

I searched the mailing lists and saw a request for something like this
in 2008, but as far as I can tell nothing has ever been implemented.
Is there a solution I am missing or do I need to implement a wrapper
tool that would do this as opposed to using a workflow?  Thanks!
