This is the RowStatus control specifically for one transmit-band entry within the MCM profile, letting an operator add, modify, or remove an individual frequency-band definition without having to rebuild the entire profile's set of bands from scratch. It matters when a provider needs to add a new spectrum notch to an existing, already-deployed profile, since this row-level control lets that be done incrementally. Setting this to createAndGo for a new band while leaving existing bands untouched is how an operator would add a single new frequency exclusion to a profile that's already in use on live lines.
