Update Data table during gameplay

So, I’ve found a a lot of entries both on this forum and on the answer hub all requesting that we be able to edit data tables during play.

Some have suggested that this would be implemented in v16 (posts from back in 2014) though I personally can’t find a way to do it.

It would be SO convenient to be able to do this and save me hours of work.

Could someone please explain to me why this hasn’t already been done (I’m not being funny, i genuinely don’t understand why not)

Also if there IS a way to do this via BP, please do share.
