Since the Data Warehouse Request Manager is univeral across suites, it makes sense that when in a Data Warehouse Request users should be able to switch the report suite without clearing out all previously filled out data.
This has been an issue for a long time. Every time I build out a query that I want duplicated to another report suite, with the same information, and I flip report suite, I know I'm going to have to spend minutes repopulating the query. It should not be this time consuming and difficult.
I imagine most customers have a dev > prod situation. We in particular have two report suites that have identical configuration. Both would be solved with this quality of life improvement for customers.
