Check out the 2 commands on the left in the operations window (the “G” and the arrow thingy)
To do a pause like what you are talking about if you have operations separated by layers, put a G-Code M0 command between each operation.
To do a move - use the “move to a given coordinate” as needed.
When you post process, these steps will be :built in" to your job.
Hope that helps!
