There was a problem hiding this comment. Could these strings be defined via placeholders instead? Or is GWP already aware of this new authoring pattern?

There was a problem hiding this comment. waiting for GWP to confirm if they will take this update, but I saw that the feds placeholders sheet isn't really actively used? And putting it in a consumer's sheet feels tricky as this lives in Milo and shared by both cc and dc, so I thought that carrying the strings inside the block feels more self-contained and easier for localization. But maybe there's a separate sheet I can use? Is there another |
