For developer:it hard to download database when install biobakery_workflows

Dear developer:
I’m a user from China,I found it hard to download database when install biobakery_workflows, and I guess this is due to regional network restrictions of China. However, I can easily download the same database from National Microbiology Data Center of China. That may help, but i get into trouble to figue out how to install database manually and properly. For example, Setting environment Variables is actually no use. So I wondering if you could add a function to Indicate the path of the compressed package of database so that i can use command $ biobakery_workflows_databases --install $WORKFLOW and use local package to install databse.
thanks for your reading
