Caching input selection

If the output is changed, the input selection field updates to default - all inputs. For a situation when a dataset has multiple outputs and a fixed set of inputs - it would be way cooler to have the input selection not changing when the output is changed.

No file or test is identified in the issue. Start by locating the UI handling the input selection field and output changes, then verify behavior with a dataset that has multiple outputs and fixed inputs; changing the output should preserve the selected inputs instead of resetting to all inputs.
