Could the Pie Chart value Prefix/Suffix formatting functionality previously available in ArcGIS Dashboards be added in future releases of ArcGIS Experience Builder?

Many of my customers have migrated their applications to Experience Builder and are concerned their charts don't clearly communicate their intent without this. The metrics depicted are not always obvious to their consumers. They require the ability to clearly define the unit of measure eg (Currency (£,$), Area (m2, Hectares).
I have trawled the community but cannot find any current variable workaround, and have to resort to detailed descriptions in the Chart Title/Description to ensure the charts values are clearly understood.
