Vendor rules sharing

Hey there, 

I’m not available to comment on the post from a year ago and I have follow-up questions:

Mike Blomgren in his reply stated that in order to “share Alert Rules with User Groups, you need to Clone the Vendor Rule”. My questions are as follows:

1. Does it work the same way with the “Vendor rules”? Is there an option to share the “Vendor rules”?
2. If so, is there an available solution to share multiple (like 50 or more) vendor rules? Do you have to clone them all?

Thank you in advance.
