Not to get too wrapped around the axle here, but my response was to @acidrock23’s suggestion for a bed-time correction for a high. You are describing a different scenario.
I totally understand that insulin delivered via a pump makes basal/bolus somewhat meaningless if you are trying to deliver a certain amount of insulin over time, and I have used all of the options (TBR, square wave, dual bolus - which on the Roche is laughingly called a multi-wave bolus).
