Importing K1s

Why doesn't TurboTax have an  import section for K1s like they do for 1099INT, 1099DIV and 1099B. I can't be the only taxpayer who invests in a large number of master limited partnerships which all are now online and can be downloaded. I find it frustrating that the lack of instructions and help on this matter has not improved after so many years. There should be a import section to give you option to import or manually enter the K1s. How hard can that be?? You cant find anything regarding it  in

the search engine. Which really surprising!  See pics!
