Clustering symbology - automate numeric labels in Layout legend?

Hello all,

Wondering if anyone knows of a fix for this, or if I should consider submitting an Idea - from some googling and LLM prompting it doesn't seem to be an option currently.

When setting up Clustering Aggregation for a feature layer of points, the symbology legend in the Map Contents will automatically adjust the upper and lower label with the numeric value (i.e. the number of features clustered) that corresponds to that symbol size when changing the scale or clustering parameters. However, when using the same layer in a Map Layout, the numeric values are replaced with qualitative labels in the Legend - e.g. a range of 2 - 200 becomes a range of "Low" to "High."

I want the legend in my Layout to automatically adjust the numeric labels the same way the symbology legend in Contents does - if the auto adjustment can be done in one place, it seems like it should be easy to have it done in another.

Thanks in advance for any suggestions or insights!

There isn't an option to display that currently, but I think it would make an awesome ArcGIS Pro Idea.
