Always be prepared to challenge requirements if you can suggest a better way.
Do not confuse a requirement with a proposed solution. The requirement in this instance is to be able to set the schedule for process chains. The solution proposed is "download, modify in Excel, upload".
Years ago, I was asked (by a FICO functional analyst) to make a report downloadable, so that the users could cut and paste the report results from excel into the selection screen of another report. Both reports were custom. I suggested that perhaps they'd like the first report modified so that it could directly call the second report with the selected data. The response was "wow - you can do that?". The users were delighted with the new solution as it made their lives so much easier.
Developers can (and should) have a role in improving user experience. Be proactive.
