Installing Themes/Plugins By Uploading Zip File From Localhost MainWP Dashboard

Many of you here might be using the MainWP Dashboard from Localhost Setup as I do.By any chance have you faced the following issue?Which is while installing a theme/plugin if we have the Zip file to upload it don’t work, because of localhost not having access to external traffic.One possible solution to this can be having a cloud integration like Google Drive, DropBox etc.So that we can upload the zip file to the cloud and all the child sites can access the file from the cloud. The same way Remote Storage backups work.If it makes sense, Please Upvote.
