Thanks @abureaux !! I'm so.so.so close to having this done and am very grateful. I'm still stuck on two things:
First, I can't get the summary map of all points in the report to look right. I've been playing around with a ton of permutations based on the info below (source link).
By default, a map question will display using a default map symbol, regardless of symbology set in the feature layer. You can use thedrawingInfo method to extract and use the drawing information stored in a specific feature layer, including the symbol, label, and transparency used. You can specify this information either from the current layer or from a specific feature layer through a provided URL.
${location | drawingInfo:"currentLayer"}
${location | drawingInfo:"https://.../FeatureServer/0"}
I've attached a word doc trying to track the trial and error outcomes. It's a bit messy but it all ends up that I can't seem to get the desired symbology output (box style point with label of "pointnum").
Second, the "dot notation" worked beautifully and allowed me to edit the caption text. It's *perfect*! I tried using it to achieve the desired photo point sorting in a couple ways without success. Am I trying to do something that isn't possible syntax-wise?
${#images | orderByFields:"Baseline_Collector.pointnum ASC"}${Baseline_Collector.pointnum}${image_alpha | getValue:""}) ${ Baseline_Collector. image_text}. ${image_text2} facing ${photo | getValue:"direction" | round:0} degrees
${#images}${Baseline_Collector.pointnum | orderByFields:"Baseline_Collector.pointnum ASC"}${image_alpha | getValue:""}) ${ Baseline_Collector. image_text}. ${image_text2} facing ${photo | getValue:"direction" | round:0} degrees
