Support an analogue to the "step" PI Point attribute when creating PI Points
Even though it will indeed be useful to be able to specify whether data should be retrieved in a step-wise fashion, for new PI Points (assuming you're writing data to a PI Connector), it's important to be able to specify that those tags should have the step attribute set to true, so that the step option is set at the central, database level where it can apply to all users who query that PI Point.

This is being developed as part of the OMF v1.2 implementation of the “interpolation” mode for properties.

This would be very useful as a minimum implementation of the broader idea posted in this feedback item:
