Use custom folder when creating account

By the past, I have created account with Nextcloud on many computers. Now I discover a missing feature I used before: I was able to designate a specific folder for each account (to avoid “Nextcloud”, “Nexcloud2” etc which are not very informative). I know that it is possible to do that when creating a account, except that it does not work (anymore) for the following reason. When I create an account, Nextcloud asks to connect with the browser to the cloud address and to accept the connection there. Then it creates automatically the account, without giving the choice for the folder on my computer: it choses “Nextcloud” or “Nextcloud2” etc (I have 2 accounts to create). Strange behavior! This is a feature or a bug? Any help is welcome. Thanks in advance. Thierry
