Automatically generate circuits on its own by vectorization

Dear all,

 Is there any way I could program the Matlab/Simulink to be able to automatically generate circuits on its own?

For example, I need to have hundreds of identical block in a single .mdl file, instead of inserting one by one by myself by calling the block which I previously saved in Simulink library, is it possible that Simulink can be programmed to automatically generate hundreds of blocks by itself?

The only way I was told is by "using vectorization for most components. Most components are vectorized if they have a vectorized input signal or if one of their parameter is specified as a vector." However, I could not find any further information/details, appreciate if anyone of you could give opinion on this? Thanks!

I just want to know if this is possible? Else, I would have to try another approach?
