Create individual versions of a gate for each file using tailored gates.

To turn on tailored gates, select an existing gate and click the radio button for "Tailored Gates." At this point, the gate will look the same for all files. However, if you move the gate on the current file, then switch to the next file, you'll see the change.

Tailored gates have to be changed for each individual file. If not changed, the gate will stay where the original global gate was drawn.

Note: moving the percent flag counts as "changing a gate".
