Deleting multiple instances of a cell from Layout

Hello,

Is there a way to delete multiple instances of a cell automatically in Layout L/XL? (like select * -> Delete)

I am manually deleting PC end cells from my layout from the right and left edges and have a huge design with multiple (>7) power domains. So, it is becoming very difficult.

Please provide me a quicker (smarter) technique for this.

Thanks,
Kashif
