Is there a way of being able to dynamically select (i.e. during simulation) an element from a matrix using standard Xcos blocks, without using Scilab or C code?

I’d like to supply the row and column for a matrix using integers during a simulation, but this could change after an event. I could use the ‘EXTRACT’ block, but the configuration values are static, not dynamic. Anyone know how I could do this?
