Grid lines inside a rectangle?

[Jennifer Murphy]

Is there a way to define a rectangle shape so that it will have "grid"
lines inside the shape at regular intervals?

For example, can I define a rectangle that will have vertical dotted
lines of specific weight and color every 0.25"?

Have a look at custom fill patterns.
