Talk:Modding: Making a custom material

When setting up a reaction, is there a way to make input_cell1 require multiple tags?

For instance,

 <Reaction probability="10"
   input_cell1="[frozen] AND [box2d]"	input_cell2="material1"
   output_cell1="material2"		output_cell2="material2"
   >
 </Reaction>

Thanks!
