Y-axis Custom Lebel Feature request in Vizlib Combo chart

Hi There, 

Hope you are doing good. We are using Vizlib Combo chart and have a requirement to show the label name in Y-axis which we are unable to achieve with current available options in Dimension Title of Y-axis. We have couple of expressions in chart but we need custom label in Y-axis which shouldn't same like any expression label. We found this feature available in Vizlib Line chart so if you would provide us same in Vizlib Combo chart also, that would be very helpful. 

Thanks & Regards, SCI Qlik Team.
