Rise - change size of headers and lesson titles

When bulding courses in Rise I've noticed that it's impossible to change size of the header space (top marigin) or font size of the lesson's title. What I woud like to do is to get rid of all the empty space between the title and the first block of content. In the attached phot I marked the areas that I want to be able to edit. The final goal is to avoid scrolling down the page when I insert a Storyline block to Rise or just any other block of content or interactivity. I already turned off Previous and Next buttons from navigation and removed all padding from content blocks but it's still not enough. Does Articulate360 team consider adding such functions for editing marigins? Thank you
