14710	Support correlation between attributes	Barnes38	team	"Hello
 I wish we can correlate two attributes, for example (fictitious example) 
<item name=""Totem"" icon=""images/Totem.png"" type=""node"">
     <label text=""Characterize a 'totem'"" />
     <combo key=""size""
        text=""Size (width*height) without support""
        values=""1.2*5,1.2*6,1.2*6.5,1*7,1*8""
        default=""1.2*6.5"" />
     <combo key=""height""
        text=""height of the highest part (with support)""
        values=""6,7,8,9,10""
        default=""8"" />
</item>

If ever the user chooses ""1.2*5"" for 'size', then the 'height' is automatically changed and proposed to ""6""
If ever the user chooses ""1.2*6"" for 'size', then the 'height' is automatically changed and proposed to ""7""
If ever the user chooses ""1.2*6.5"" for 'size', then the 'height' is automatically changed and proposed to ""8""
If ever the user chooses ""1*7"" for 'size', then the 'height' is automatically changed and proposed to ""9""
If ever the user chooses ""1*8"" for 'size', then the 'height' is automatically changed and proposed to ""10""

Today the values are proposed to their default, but if the user changes one of teh two values, he has to manually change the second value as well. 

Thank you to tell me if this already exists (maybe), or if this is something which is possible!
Thanks a lot!!
