Hi @judy s thanks for posting in the community! It sounds like the Group function may be helpful for what you're trying to achieve. To do this you can add the QR image to your document and place it in the position you'd like in the process box. After this drag a selection box around the process box and QR image then right-click and select 'Group' from the menu. 

Once the image and the process box is grouped together you will be able to move them together. 


Please let me know if this is not what you are looking for or if you have any additional questions. Hope this helps!
