How to create a "detachable" part on my circuit?

My question is the following :
I created in Fritzing a circuit board that consists of two parts.
One on the left and one on the right, they are separated by a dotted line (text object).
In some cases I would need both parts, but in another case I would like to be able to remove (detach, separate or easily cut) the right part which I don’t need.
I wonder if there is a function or object in Fritzing to create a “detachable” part
(with small holes or pre-drilled slots)
Thank you for your help.
