User home directory creation case insensitive

Hi,

I have a Dataset named "USERS".
This dataset have a child named "JOHN" (in uppercase) ==> ./USERS/JOHN .

I want create a user named "john" (in lowercase) with the Web UI :

If I choose the dataset "./USERS/JOHN" for his home directory, the Web UI creating a subdirectory named "john" under the dataset "JOHN" ==> ./USERS/JOHN/john . It's not OK for me.
But if I choose the dataset "./USERS" for his home directory, the Web UI accept ./USERS/JOHN as home directory.

Can you disable the case sensitive when then Web UI do the comparaison between the username and the home directory path to accept ./USERS/JOHN as a valid home directory for the user "john" ?

Kevin.
