If the user wants to freely modify the register maps without the tools, they can do so using the Edit Source button. They can also copy from it and paste into a CSV file to modify there.
To do that, the user would first select the register map to edit on the left side menu under Register Maps and select Edit Source.
Once selected, the user will be prompted with the below popup to make any edits or copy to CSV.
Once changes are made, they can save them by selecting the Save button.
