Welcome to the Q&A Forum

I finally heard back from Google - the issue with bulk uploading directly into Google My Business is a known issue that there is no fix for (at least not at this time). I was advised to continue to add each location manually, waiting out the clock when I added too many listings in a period of time. After a while and a lot of typing, I was finally able to get all of my listings into my account in order to apply for bulk verification. Thanks.
