Software :: Safari - Open Bookmark Folder In New Tabs

Firstly, my apologies as this is a topic that I've seen posted several times. Unfortunately, I haven't actually found an answer/workaround after searching a few different forums sites. I've been using Camino as my primary web browser and have generally enjoyed it. However, my one real frustration is that every PDF I open has to download and be displayed in Preview rather than native within the browser (skimming lots of journal articles on PubMed becomes very tedious this way). As such, I was very excited to switch back to Safari when I saw that it can open PDF files in tabs. And this bring me to the whole point of my post: How do I open a folder of bookmarks (e.g. from the bookmarks bar) in a new set of tabs without getting rid of all my existing tabs? Camino and Firefox both offer this option and I find it really essential to my way of browsing the web. I don't want to open a new window just to view an entire set of bookmarks (the point is to keep them all open in one window) and I don't want to manually open each page in a new tab.
