putting a block inside an already created block

Dear friends,

I have a wing with hex mesh around it and that mesh is quite good for this geometry (Thanks to Far!).
But now I have come to a difficulty! I have modified the wing geometry by creating a slot on the upper surface and now I need to mesh inside this slot either. The slot is a quad prism oriented along the span. The problem is that I don't know any simple way to perform meshing without recreating the whole blocking.
I thought of adding a separate new block inside the slot and mesh it, but that didn't work since ICEM could not handle it. I have also attached a couple images of wing with slots and current blocking.
Could anybody solve this problem? I would really appreciate.
Thanks.

Thank you Far!

I see, but since I have modified the geometry, there is no vertices at the corners of the slot! How can I produce these vertices?!

Then add the splits that you need for the slot and adjust mesh sizes. syavash likes this.

Now choose any 8 locations in some logical order (see help). Now merge them with existing blocking. You may need to make some splits in main blocking ...

Sorry Far, I cannot get you! How is it possible to select vertices while we do not have them?!
