Is there a way to have conditional attributes?

Such as, if an item is a certain size and a certain color, then it can only have a certain fitting, while choosing a different size or color, lets it have a different fitting?

For example, I have a lamp shade that has 5 colors and 6 sizes.

for a 10" in any color, it can have fitting WA,
for an 8" in 4 colors, it can have fitting WA, but for an 8" in the last color, it only has fitting CL

I have several products like this, and I don't want to have to create a separate product just for them, as I just got done ridding myself of 200 duplicate items that were only different by attribute...

I also have a few products where the lamp shade is available in some colors for one size, but different colors for another size...

Nevermind... I found the answer on a search... sigh no conditional attributes yet.... soon I hope???????????????

Seems a lot of people want em, and they definitely would come in handy, since I'll have to create duplicate products for the "odd" attributes.
