copy and paste with different names
When you have to resize a field such as a check box, it is more efficient to do a copy and paste. However, it is a pain to have to go back and edit each and every field with a unique name. This occurs because your paste autopopulates the name field with the same name. This feature should be able to be turn on or off as needed.
Closing this for now until we have further info on the request.
Can revisit later
On right click of Check box, you can click "Create Multiple Copies" option and you can have multiple copies which will have different names. Now you can place all these copies anywhere on the page by dragging.
Hope it works for you.
