On your website you say Split Spacebars are a customizable option. I could not find that option on any of the models’ ordering forms. From a previous question 4 years ago, you stated it was not an option from the factory. Is that still the case? If so, what “extra’s” packages would I need to buy to do it myself, and would it be hard to do? I want to use my left thumb for backspace, right thumb for space. Right now Im looking at the F62 MODERN case.
