Include custom folder specific assets in ruby on rails

I am trying to create separate folders for keeping the assets related to backend and frontend. I planned the following folder structure: app/assets/dashboard/javascripts instead of the usual one app/assets/javascripts.

Backend is served via app/views/layouts/dashboard.html.erb, and includes the assets in the following way:

<%= stylesheet_link_tag 'dashboard/dashboard', params[:controller], media: 'all' %>
<%= javascript_include_tag 'dashboard/dashboard', params[:controller] %>

Front end is served via app/views/layouts/application.html.erb, and includes the assets in the following way:

<%= stylesheet_link_tag 'store/application', params[:controller], media: 'all' %>
<%= javascript_include_tag 'store/application', params[:controller] %>

I am not sure that what is the correct way to include the assets in this way, and hence getting 404 not found error for http://dashboard.localhost.com:3000/javascripts/dashboard/javascripts/dashboard.js in the console

I've also tried changing the scripts path to <%= javascript_include_tag 'store/javascripts/application', params[:controller] %>, but it doesn't work either. Also tried adding the following piece of code mentioned here to application.rb, but it didn't work either:

Dir.glob("#{Rails.root}/app/assets/**/").each do |path|
      config.assets.paths << path
end

With these settings the paths populated in the console are as follows:

[9] pry(main)> Rails.application.config.assets.paths 
=> ["/home/vipin8169/projectRoot/inmonarch_website/app/assets/images",
 "/home/vipin8169/projectRoot/xyz/app/assets/javascripts",
 "/home/vipin8169/projectRoot/xyz/app/assets/stylesheets",
 "/home/vipin8169/projectRoot/xyz/vendor/assets/javascripts",
 "/home/vipin8169/projectRoot/xyz/vendor/assets/stylesheets",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/jquery-rails-4.1.0/vendor/assets/javascripts",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/coffee-rails-4.1.1/lib/assets/javascripts",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/react-rails-1.6.2/lib/assets/react-source/development-with-addons",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/react-rails-1.6.2/lib/assets/javascripts/",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/bootstrap-sass-3.3.6/assets/stylesheets",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/bootstrap-sass-3.3.6/assets/javascripts",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/bootstrap-sass-3.3.6/assets/fonts",
 "/home/vipin8169/.rvm/gems/ruby-2.2.3@rails426/gems/bootstrap-sass-3.3.6/assets/images"]

Is it supported in rails, altering the assets directory structure in this way?
