Group runtime parameters in workflows

I have developed a workflow with more than twenty parameters. During Request submission from the catalogue, it is quite cumbersome to handle such a large number of parameters. Some of these parameters are related.
Does process studio have any feature to handle this in a neat way?

Yes, Process Studio has a feature to handle the complexity of parameters. The workflow properties window has a Parameter Configuration option which provides a logical and hierarchical grouping of runtime parameters.
The same grouping and hierarchy are ported when the workflow is published to AutomationEdge. During Request submission from the catalogue, you will view the parameters in collapsible groups. You can now expand the groups one by one and deal with the parameters conveniently.
