Historical Asset data

Are there plans to add more asset classes?

Are there any plans to add more asset classes to the "build portfolios" portion of the Monte Carlo planning method? For those of us who do not have access to Dimensional Funds, the options are very limited. I'd like to have access to historical data for Large Cap Value, Large Cap Core, Large Cap Growth, Mid Cap Value, Mid Cap Core, Mid Cap Growth, Small Cap Value, Small Cap Core, Small Cap Growth. I'd also like to see separate options for short, intermediate, long term bond funds in both the government and corporate sectors. Thanks!
