Is it possible to preset variables in sass?

Question

Sass

Introductory:
1. There is a hierarchical build structure, in which sass are each in their own logical folder.
2. There is a config file in which variables and mixins are pre-installed
3. Files cannot be glued or included (at least part of them), they are needed as independent css files as a result of compilation.
4. Now, in order for common variables and mixins to be available in separate sass files, you have to write something like include '../../../../../../../config in each separately .sass' =)
Question: is it possible to pre-set a variable at the sass level or autoload the config file?
For example, some kind of path variable to be defined, say, at the gulp-sass level, into which to sew the absolute path to config.sass.
DECISION
It was suggested by Sergey Sergey in the comments.
In a piece of code below, we add the path where Dmitrijs Balcers will look for include files.

.pipe(sass.sync({
  includePaths: [process.env['INIT_CWD']+'/assets/sass/global/']
}))
