Hey, im pretty sure you are looking for the layout guide feature. Its placed in the right side panel when you click on a frame.
 

You could also set them up as a style in the right side panel. (Click on a blank space in the canvas, if you cant see the file options) After the style is created you can apply it via the icon left to the “+” seen in the screenshot above.
 

With shift + G you can toggle the guides on and off.
