Some questions about the carousel object

Hello,

I think it is not possible to configure a non circular carousel, isn't it?, i.e., I want a carousel with 13 cells, but when the user is viewing the cell 13 I don't want the cell 1, cell 2, and so on to be viewed as the next ones.

If this is not possible, I am thinking this:

The user can see 5 cells (I am using an horizontal carousel) and the focus is in the 3rd cell. What I want to do is when the focus is in the 3rd cell, the user can't move to the cell in its left. Is this possible? The user only can move to the cells in the right until he reaches the third from last.

Is this possible?

Thanks in advance!!
