Hi there thanks for posting in the community! You can use containers to accomplish this. To access containers click on the containers icon in the Primary Toolbar. You can choose from a single square container two rectangle containers or four square containers.

After adding one to your canvas you can add objects such as shapes sticky notes text and freehand drawings to your containers by clicking and dragging them into the container. The container magnetizes its contents to it so you can move everything together as one organized group.

For more information please view this Containers help center article and post any additional questions below.
