I wonder if the premise of the question is in our best interest. This was my answer to him.
One answer might be that in order for us to receive new light, we must be willing to live according to the light we have received. It is possible that you, personally, are living according to the light you have. That you have received a personal confirmation about some new light not available to the church or world generally.
That does not mean that you have the authority to speak for the church. Or even the right to convince the world or Mormons of your new revelation, whether it is actually true or not.
Asking the First Presidency might serve to distract from the most urgent needs of the church generally.
This scripture came to mind
"if ye were holy I would speak unto you of holiness; but as ye are not holy, and ye look upon me as a teacher, it must needs be expedient that I teach you the consequences of sin." (2 Ne 9:48)
"We cannot and we must not allow ourselves to get distracted from our sacred duty. We cannot and we must not lose focus on the things that matter most." ("We Are Doing a Great Work and Cannot Come Down", Dieter F. Uchtdorf, Apr 2009)
It is not up to us to direct the church. It is not up to us what questions the First Presidency ought to be considering. If you feel a burning desire to advocate for a certain revelation to be received; if you feel God is calling you to make this come to pass; you are free to do so. Just do not expect the Brethren to feel obligated to answer you. Do not expect that you are free to do so without possible negative consequences.
If you are a sufficient distraction to the work of the Lord as discerned by those with the keys in your local area, they have the right to censure you as a Mormon.
