How can you add a custom detail type in accounts with the online version of QB?

This question was asked over over a year and a half ago.  Certainly before then. 

This is BS BS BS BS.  This is no only a simple fix, but one that every business owner needs and I am sure is as frustrated as I am for the lack of intuitiveness for a company called intuit.  Do you really think that the magazine stand in New York City has the same two dozen categories as the trucking fleet in rural America?  They call it logistics for a reason.

And, YES, I have tried your backdoor fix..." However, you can create a sub-account and match it to the closest parent account."  It is tediously frustrating and counter-INTUITive!!!

INFURIATING!
