virtualmin different virtual server account permissions with each other directories

Hello, i am using virtualmin to create subdomain accounts for diffrent virtual servers (accounts in the system), i created in the system. i have an issue when a one of the virtual server user "utility.maindomain.com" (the utility virtual server account that handle cronjobs and other stuff) trying to do a git checkout on an existing different virtual server account "blog.customerdomain.com". this gives me permission denied issues, which after all sounds logical. is there any way to let a virtualmin user (virtual server domain account) permissions to use git checkout on a different user in the virtualmin system ?

thanks!
