Place multiple labels for overlapping features

[Theoc72]

I am currently working on an ArcGIS Online map that contains water rights data joined to the quarter quarters of the BLM's Public Land Survey System. Each quarter quarter may contain multiple unique water rights, creating multiple features that share the same location and geometry. In ArcGIS Pro, this was not an issue, because each quarter quarter could be labelled to list the different features/water rights (see attached image).

 

However, in ArcGIS Online, each quarter quarter will only show the label of one feature. 

Is there any way to force all labels to show using either the map viewer or experience builder?

It is important that the features all remain separate but in the same feature class. I know that people will be able to click between the different features on the online map, but for staff printing maps it is important to fix the labelling on the online web map.

Is the water rights data a single feature service or multiple feature services? It kind of sounds like instead of labeling the BLM Survey layer, you  build a label expression that spits out one label from multiple columns in your water rights FS. This is some lazy pesudo code but something like

var txt = ""

IF($feature.RIGHTS1 != "") {txt = txt + $feature.RIGHTS1 + TextFormatting.NewLine}

IF($feature.RIGHTS2 != "") {txt = txt + $feature.RIGHTS2 + TextFormatting.NewLine}

IF($feature.RIGHTS3 != "") {txt = txt + $feature.RIGHTS3 + TextFormatting.NewLine}

return {

  type : 'text',

  text : txt

}
