Freeze Layout with in Bloom

I am comparing community algorithms such as pageRank, articleRank, and Betweenness. For my exploratory investigation it would be really nice to freeze the locations of the nodes within Bloom. I am using styling rules to highlight the important nodes and I would like to compare and contrast between the different algorithms. I am having the values written to the same property variable and would like to get a feel for the changes and what each one does visually. However Bloom has the habit of repositioning at will even to the point I cannot click on a node because it is running away. Is there a way to freeze the locations and then just allow me to apply different styling runes?
