Confirming: you want to put the new bloodwork between “range” and the 9/22 data on the labs tab?
If you don’t want to move the entire column (looks like you have a section below the lab work that you may want to leave where it is), you drag/highlight just the relevant 9/2022 data and “add new column to left”. That should move only the highlighted data over and leave a blank column to either paste or type in the new bloodwork, while leaving the lower section intact. Alternatively you can highlight the “Range” data and add column to the right.
