Custom Fonts in Global Blocks

In a similar thread, there is a request to use custom fonts in forms, and I saw the reply that it's in the plans at some point. I want to add to that about Global Blocks. When building courses, you cannot use global blocks for anything that requires a brand font used everywhere on the page. In light of the need to add the code to the page, it may never work, and I'll use my workaround with a template page, but I wanted to add at least that it is an issue, particularly for headers and footers where the font consistency is a major issue.
