The custom CSS we can define is on template level and cannot be reused. We would like to define some custom CSS for branding and reuse it in all the templates we do for that brand. I tried to include a block within a reusable module but as this is part of the it's not working well and when template is exported this is removed. Is there anything we can do to achieve this? Or is it planned for the future? We would like to keep brand CSS centralized so if we change them in the future all templates are affected (similar to a module for defining styles). Thank you!
