Select the dimension of a ROI in a range of selected slices

Operating system: macOS Monterey 12.5.1
Slicer version: 4.13


I need to segment a ROI (a round or square of specific dimension), located in the same position, in selected slices. I tried to use scissor but I have two problems:
1- I cannot control scissor cutting dimension
2. I cannot select the first and the last slice in which apply the segmentation.

Someone can help me please?


This sounds doable with a little python code to control the parameters.
