Yes. Click on the figure, then View -> Property Inspector
On the figire > Axes that comes up from there, in the TICKS section, you will see YTickLabel with something-by-1 cell listed as the property, on a line below YTick that lists the tick values. Click the three vertical dots to the right of that pair of boxes.
A box will pop up that lists y tick values on the left, and y tick labels on the right. You can click on one of the ones on the right and edit it (you might have to type in a complete new label, rather than being able to edit the existing label in place.)
