Plot Style Table search path

Hi,Our company uses a mixture of AutoCAD LT 2008 and Bricscad. Our Plot Style tables are kept in a network location, eg. P:\Plot Styles. Within this folder are several subfolders such as P:\Plot Styles\Client, P:\Plot Styles\Legacy etc.AutoCAD automatically locates all plot style tables in the top directory and within the subfolders, listing them all in the plot style table. Bricscad however only locates the plot styles in the top directory. Is there a way to change the settings in Bricscad to mimic the AutoCAD behaviour?
