How to change texture for build mode creative 2.0

Hey so I am making a Fortnite game in creative 2.0 and was wondering how do I change what wood looks like when you build. For example if I build a ramp or something out of the wood material how can I change the texture of it to a custom one. Thanks in advance

Anyone know even if it’s possible?

Just writing this message to get this back up to top of list to be more noticed
