Option to disable Editor Key when PIE


In my old engine, I use a lot of F-keys (F1-F12) to achieve certain task but in UE4, most of the keys are already used by Editor so they are not usable anymore in PIE.

So my thinking is, provide a new feature which provide a new hook/callback/( or even GUI checkbox in Settings) to indicate that we want to disable all Editor keys (or even better only certain keys).
Currently I read that the applications have only access to F1-F12 keys when they are packaged which make testing quite difficult.

Yes, I know I can just change the key mapping but a lot of others keys are already used for something else, and being able to use F-keys is just logical stuff to do…
