Good way to get total return data into Optuma

Hello, has anyone figured out a good way to get total return data into Optuma or a good source for the data? I have a stockcharts.com premium account, which supplies tickers of both adjusted and unadjusted prices. Is there a way to get those tickers and data into Optuma?

I also pay for DTN Feed in Optuma.

I suppose I could manually upload the adjusted prices in excel, but I would like the ability to analyze a bunch of securities with prices unadjusted for dividends.

Anyone know of a good data source that works?

Thanks for the help.
