Modifying cut settings for inlay

I am trying my first inlay design in easel and have a couple questions. I have created a design and used the inlay generator but I need to change a few things. Is there a way modify the cut settings for the mirrored inlay piece? ie I need to “fill” cut around the horse.

I also need to remove some material around the inlay so I can cut it out and press it in. Any help is greatly appreciated.
