Import scss and use styles only if element is in parent?

Question

Sass

Hey!
styles are written according to BEM, each block has its own scss file.

there is a sidebar from the ui library, with its own styles.
if the sidebar is a child of the .dashboard container, you need to overwrite some styles, if it is not a child, then we leave the styles from the ui kit.

there is a sidebar.scss file:

.sidebar {
     &__inner {
          ...

          &:hover {
               ...
          }
     }
     ...etc
}

and there are styles for the dashboard:

.dashboard {
     ...
}

you need to somehow import .sidebar into .dashboard so that the styles from the sidebar are applied only to descendants of the dashboard. this can be done?
