Custom IMAP prefix for Vivaldi Mail

[brezanac]

Hello.
Is it possible to set a custom IMAP prefix for mail accounts in Vivaldi Mail (Desktop)?
I see that Vivaldi already applies custom prefixes for GMail accounts by adding the [GMail] prefix however I can't see to find an option to do that for other providers.
I need to be able to set a custom IMAP prefix in order to avoid weird IMAP folder stacking in my email clients.
Thank you.
