Edit existing text vanishing point

Hi,

My first post.

I downloaded a free editable Illustrator text effect file (pic below) and……

I want to: keep the existing text style (colour/gradient/stroke), which ive manage to do....

BUT I want to REMOVE: the current vanishing point (currently sloping downwards - Pic 1), and EDIT it, so the vanishing point recedes to the middle (between the letters T and B as circled and highlighted with the yellow lines - Pic 2).

Can the current vanishing point be edited accordingly, or do I have to start from scratch?

Thank you all.
