How to use different bit on different parts?

Id like to use different bit to differnet parts of image but cant understand how to tell Easel for which id like tou use 60 and 90 or straight bit. Id have duplicated the image and try to make it as a parts but not possible.

For the example:

Id like to use vbit 60 for frame but 30 for detailing the einstein.

Assemble the project completely first, then make two copies of it below and delete the pieces you don’t wish to carve with a specific bit on each copy…

As long as you don’t move the pieces they will line up properly. If they overlap you will have to consider the cut order and stacking of each piece. I subtracted the star from the triangle as an example of this.
