Hello! I’m glad that the Google Docs variant is serving you well. Unfortunately, I have been unable to find a workaround to allow the Lancer Icons to work with Google Docs. Importing the icons as drawings could work for larger versions of the icons (e.g., role and size icons for mechs and NPCs). However, from my experiments, I could not get the drawings to shrink to a reasonable size for inline use (such as in weapons statblocks). You are welcome to try on your own, but right now my recommendation for inline use on GDocs is to type out the keywords and bold them instead of using the icons. Even several Lancer supplements opt to take this route!
In all, I hope you are able to find a solution that will satisfy your needs. I wish you the best with your creations!
