Trying to implement some changes to the base monk class for my campaign, is it possible to make edits to the base features or only create a subclass?  I would like to make Dash/Disengage a bonus action with no Ki cost, and still leave the step of the wind with 2X leaping a Ki ability but make it last for 1 minute.  this is in addition to some other changes I wanted to implement.

Thanks

On dnd beyond its currently not possible to create a class.

Yeah, sorry, you can only make changes to, or create new, subclasses in D&D Beyond. Cannot change anything of the base classes.
