Hello Tarrasque,
as you already discovered in this post => here <= swiping to the side will show the BLF screen.
There is at present no way to modify the GUI and a feature request via your Polycom reseller would be required.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
