Custom Sorting of Account Names

[dersuchmann]

Hello everybody,

I have a list of account names with a (to me) canonical order. For instance assume I have 

Expenses:Groceries
Expenses:Gas
Expenses:Other

And I would like to define a sorting that puts these account names in that particular order. Alphabetical does not work, and I also do not want to insert sorting numbers like 01-Groceries, 02-Gas, 03-Other... Is there any way how I can define a custom sorting with ledger? Maybe via some complicated value expression or any other way?

Thanks a lot!
