Add Trend Line feature to Small Multiples Line Chart in Power BI

Power BI should consider adding the Trend Line (linear regression trendline) feature to a small multiples line chart.  Currently it is available for line charts but not when using small multiples. An option to generate simple linear regression trendlines- straight lines that show the overall direction of data points would improve clarity and analytical accuracy, especially for business analysts and decision-makers who rely on visual cues to interpret performance metrics.
