[O] [Feature Request] Add hook right before "org-export--dispatch-action"

[Julio César]

Hello,

currently org-mode doesn't provide a hook one could use to customize the *Org Export Dispatcher* buffer, for example changing the font face for it. For this one have to fall-back to using an advice like explained here, the suggestion is to add a hook right before org-export--dispatch-action with the Export Dispatch Buffer as current buffer to the org-mode.

Would it be possible to add such hook?
