Prioritize folders / files to be downloaded

"Sync Now" is currently only an option for individual files. I have TBs of files in my Dropbox. I know it's a lot to sync & I didn't want Dropbox to have to download them all onto my new computer. So when I transferred computers, I copied most of the folders onto my new hard drive. The issue as I've found is that Dropbox performance isn't optimized for this many files. So my Dropbox stopped synching. It's stuck at 10k+ files, unless I add new files or click "Sync Now" on individual files. Most of the files are already on my computer. But Dropbox doesn't recognize this unless I click "Sync Now," in which case it can instantly recognize those files which are already in the cloud as well.

Most of the 10k+ files Dropbox has stuck in the syncing process are filed Dropbox thinks it needs to download. However, the vast majority are already on my computer & Dropbox recognizes them when I click "Sync Now." The issue is I need the option for folders & multiple files. This would save me from having to manually click "sync now" for 10k+ files individually simply because of a performance issue within Dropbox. I pay a premium for 3TB & expect premium service. I need my files backed up & the current "Sync Now" option limited to individual files is inadequate for my needs.
