Can new detail types be added or edited

I'm happy to share the information about the detail types, LunyBookkeeper!

We're unable to add or rename the Detail Type of an account. However, you can replace it with the other Detail Types under the Account Type you choose. Example: For the Utilities expense account, you can choose other detail types from the drop list.

I'm including the article about the Chart of Accounts in QuickBooks for your additional reference: Understand the chart of accounts in QuickBooks.

Just a little constructive criticism for the answer supplied:

For me, personally, some answers get convoluted and confusing when you offer "solutions" that don't really apply to the question. In the current case, the question was simple enough and the answer should have been a simple "No, sorry, it's not modifiable at this time"...or something to that extent.

To  add anything to the simple answer forces the reader to take time to "explore" the "solution/work around" provided when in this particular case, there really is no other solution or work around.

Thank you, though, for all your answers and insights to these questions.
