First off I don’t use easel. I use the Universal Gcode Sender with Gcode created by other software. That said, you can save your Gcode( the instructions the router needs) in a text file. You can also set up simple fixtures to position your work for multiple pieces. These can be as simple as straight pieces of wood carpet taped or bolted down to the table. Then using the wood to position your work, and using the Gcode in Easel you should be able to do repeats. At worst, you may need to rezero your bit to the material.
Many folks here call what I would call a “Fence” a bump stop.

This gives you an idea of how to use a fence and clamps for positioning.
