Big “maybe” on that 
Macros are all plain text, and anyone can get at them and mod them. In this new update they are WAY more modular than they are now. Each “function” has it’s own macro, and then there are larger macros that orchestrate the smaller ones.
In theory this makes them much easier to mod. Let’s say there a particular function you want to tweak you could find that macro and tweak it. If you want to make fundamental changes to the orhestration of things, that might get harder just because it could take a bit of research to see how everything works together.
However! The hope is that you won’t need to actually do that. We’ve tried to think of every use case and hopefully there’s a setting in our menus that you can change to get what you need so you don’t have to resort to editing code
