Suppress part of a running header
I have a functioning running header: <Chapter> | <Phase> | <Tool>
but there are some pages where <Tool> should not appear between the last tool and the next Phase or Chapter.
Also: The Chapter will change but it still shows the old Phase (which no longer applies) until a page with a new Phase.
Is there a way to set a <Tool> textbox so that it appears blank or invisible or just suppressed entirely or do I have to put a clunky rectangle over it to hide it?
I tried adding a Tool text box with only spaces hoping it would trigger a change to a tool showing "blank space" That would be too easy, right? But spaces are not recognized at all so the previous tool still appears.
Any ideas? Thank you for your attention
