Portal Feature Symbology based on Related Table

Question

I see that, in Portal, I can add a count of related tables to a point feature's pop-up in the map.

I have a point feature with two related tables, one for investigations and one for repairs.  Is there not a way to symbolize the point feature based on the related table record count?  Something like:

Symbolize the feature this way if # of Investigations is 0 and # of repairs is 0

Symbolize the feature this way if # of investigations is > 0 and # of repairs is 0

Symbolize the feature this way if # of investigations is > 0 and # of repairs is > 0

I know I've seen other discussions stating you can't symbolize based off related tables without some scripting, but it seems like if I can add it to the pop-up, I should be able to use that info to symbolize as well; however, that doesn't appear to be the case when trying to change the point's symbology.

A script could be written to do this, but you would need Windows Task Scheduler to execute it on a given interval (i.e. execute the script every 30 seconds to check for related records).  GeoEvent is a solution for real-time GIS that will perform an action as soon as an update occurs.

Could a script be written that would auto-populate a 'Last Inspected Date' and a 'Last Repaired Date' attribute of the point feature with the dates from the most recent related tables?  When a point is added, these attribute values would be null, but once a related table was added, the date would auto-populate with the date entered on the related table.  Then you could symbolize based off that attribute field (if the last inspection date is null, color is red - if last inspection date is > 0, color is orange - if last repaired date > 0, color is green).

You're correct.  It doesn't look like you can tie into related fields, but it appears this functionality is coming:
