Modify Grid footer information ("On Hand X, Available Y, ...")

Question

Is there any way with a customization to modify the information area at the footer of a grid particularly the Sales Order Entry > Document Details grid that displays On Hand & Availability information for the Current SOLine?

Answer 1

    public virtual void SOLine_Availability_FieldSelecting(PXCache sender, PXFieldSelectingEventArgs e, PXFieldSelecting invokeBaseHandler)
    {
        invokeBaseHandler(sender, e);
        e.ReturnValue = "Hey There!";

    }

Availability seems to be a common descriptor/field for several line level DACs
