Today Creo Illustrate is too limited when it comes to working with large contexts that require filtering to find the parts to include in the figures etc. Also the EBOM is lacking all metadata displayed in the tree so it's very hard to locate parts based on metadata to bring in to the SBOM.
Add alternate partname on the EBOM like existing alternate partname for SBOM.
Add filtering functionality on specific attributes using Regext or Wildcards for both SBOM and EBOM. (Same as in Creo View MCAD)
