In FrameMakers, the Index Markers are actually hidden from view. How to add globally “@@@” at the beginning

How add globally “@@@” at the beginning of the Index Marker and “@@@@” at the end of the Index Markers.  If any easy way to do this

I find it easier to just turn on Text Symbols and then give my marker symbols a bigger size & different colour so that they stand out more.
