Copying one filter into another?

Is it possible to copy an entire filter into another? For example I wanted to use one pattern I am happy with as the mortar of another complex tile pattern filter, and still be able to adjust the mortar. I can copy the nodes from one filter to another, but it appears that there can only be one "result" node. I would like to retain the filter controls that are available in the result node for both filters when I combine them though. Am I missing another node that gives you the same options as the results node?

You could add a Switch right before the result node.

Don't understand why you'd want this though. Can you explain with example filters, what you're trying to do?

Thank you folks, and thank you Kraelin for explaining the terminology. Unfortunately my trial has expired and I did buy the 2.0 pre-order but haven't yet figured out whether or how I can continue using the trial until release, so I can't show examples. In simple (and perhaps technically incorrect) terms however, the reason I'd like to do what I asked is that I created a nice gritty looking texture that I'd like to use as the grout for a separate tile filter, which utilizes parts of the Results component (like the Reflectivity setting) to give it the sparkly, sandy appearance I wanted. Without the Results component the texture is flat. I would like to retain the ability to adjust various parts of this grout texture (plugged into the Mortar node of the Tile component), like the color and noise scale, etc. and simultaneously be able to adjust all of the Tile component attributes. Perhaps this particular example isn't the best, but what I'm trying to discern is whether any of the adjustments available at the Results level like Reflectivity are available as a separate component, so that I can custom build a filter by reusing parts of other filters this same way.

Thank you again, and please forgive me if I'm still being dense, but when I peeked at your Mesh Granite filter (beautiful!) it looked to me like the reflectivity input and metallic map controlled only the "shinyness" of the metal grate, and the colorful texture underneath seems unaffected by those adjustments. What if I wanted to make the granite texture beneath have a metallic or reflective look to it, and also have the grate look metal?

select Blur tool with radius zero to use as render point for all previous filter coponents and proceed with ur further components and save as in the file menu!!!
