Hello Carlos,

There is two possibility, the one is that we going to make new dominator restyling template with more positions at the top, where you may place any vertical login module (not joomla core but the one from the JED there is a bunch there) but this template will have dramatically different positions and its names

The other variant make the cusom template work to your version of template even posibly the  very simple customization is adding another top position for mentioned vertical login modules. If you think that its best for you than contact with Konstantin and provide more details about what you would love to see for you own.

Best Regards!
