You could save much data in one LocalStorage if you seperate it later with the mid(text,index,count) command. Text is where you get the value from.
index is when you have "10 20" as value then if the index is 1 it means the 10. Then count means how many characters you want to get.
Example:
Value from LocalKey (Key): "Hello World"
Seperate it and put that in Variable2:
Variable2-> Set Value-> mid(WebStorage.LocalValue(Key),2,5)
With that code the LocalKey: Key will be seperated and the word World will be put in the Variable2.
I hope I could help a little
