You can adjust the bleed in the 1up, and then, in the layout drawing, spread it across all layout 1ups.
To adjust the bleed in the 1up
The 1up changes its appearance, displaying the places where bleed adjustment can be done.
TECHNICAL NOTE: Bleed contour modification takes place when you click a marking and then drag it in the direction you need. If you need to transform the available lines and markings, further modifications are available: (1) For squares, pressing SHIFT + mouse click removes the square and merges the two lines that it links into a single line; (2) for cross points, pressing SHIFT + mouse click breaks up the line into two and turns the cross point into a square.
A contextual edit bar appears above the graphical area.
The bleed in the layout 1up adopts the changes made in the 1up drawing.
The changes in the bleed are now applied across the layout.
