Best Approach for grouping KML layers for use inside a web map?

[RYANCARL]

Hello all,

I am looking for a solution to a organization problem that our team is having. 

We have a few KML files from external (consumed by URL )sources and a few KML files that we create internally. We are looking for a solution to group them for use inside the Experience Builder or possibly the Web AppBuilder. When we load them up right now the list of sources in the Layer List is very long and we would like to organize them by category.

Does anyone have any suggestions? 

Thank you in advance.

Hi Ryan,

I'm organising my Teams data on Portal as well at the moment. I think group categories might be the way to go but I'm keen to hear what other people have used. (https://enterprise.arcgis.com/en/portal/latest/use/own-groups.htm#ESRI_SECTION1_4BDBB9F2A8A3491CACF1...)
