Tuplet questions for Cubase 9.5

I want to write a tuplet over a certain amount of beats. For example, in 4/4 , I want an 11 tuplet over 3 beats. I want the grid to adjust accordingly. How do I achieve this?

How do you write nested polyrhythms? For example, in the middle of my 11-tuplet I want to have a quintuplet that began on the third note of the 11-tuplet. How do I give a second instruction to get a second-level tuplet and have the grid adjust accordingly?

Hi,

Open the Quantize Panel, set the basis (for example 1/8) and then set the Tuplet value to 11. See attached screenshot, please.
