Are you aware of cross references for Hashtags? In this situation I would mark the main reference with a cross reference saying "main", so for example:
// main:#ExampleCrossReference
void functionHoldingManySections()
{
// Alt-Shift-G on the hashtag here lists "references" and "cross-references" as sub-menus of hashtags
// #ExampleCrossReference
// #ExampleCrossReference
// #ExampleCrossReference
}
this makes sure that it gets listed separately, so you can easily identify it, and jump to it from any of the other instances of the hashtag.
