To start with, while testing a few things, I noticed that the tooltips for each Business Process Flow field was being set to the Step Name of each field. This made the workaround easier as this could be treated similar to how the Description area works. By setting the step name to a custom tooltip message the only remaining thing needed to be done would be setting the field label to the default name.
It is important to note that if the same field is located on the form it will also be renamed. To avoid this and only change the Business Process Flow labels the commented line in the code above needs to replace the line above it. This just makes sure the field label being changed is located in the Business Process Flow by checking if the field contains “header_process_”. It is also important to note that this function is written to change all labels of the field name in the cases that the same field is located multiple times within a business process flow, whether it is located in different steps, different branches, or different processes. If this is not done, the only field label changed which be the first instance of that field.
The finished product can be seen above, when hovering over the ‘Budget Amount’ field in the Business Process Flow. Hopefully in future releases this functionality is added, but until then this little work around is a viable option.
