On the gCADPlus menu you will find a tool that can be used to pass the plant schedule list to an Excel spreadsheet. Operation is simple, select the tool and the file will be written with the CSV extension.

It would not be too difficult to import the CSV schedule into a spreadsheet containing a complete plant list together with pricing. An Excel macro could easily match species name to price from another sheet. that's perhaps something we could develop.
