Is there an option to enable cellmagic on every cell?

Thanks for the docs link!

I’ve now managed to prepend a line like this:

def run_all_cell_with_magics(lines):
    new_lines = [] 
    new_lines.append("print('Hello Time') \n") #this works
    #new_lines.append("%%timeit \n") # this does not work

    for line in lines:
        new_lines.append(line)
    return new_lines

ip = get_ipython()
ip.input_transformers_cleanup.append(run_all_cell_with_magics)

and it actually prints “Hello Time” for every cell, as can be seen in this screenshot:

But that does not work for prepending %%timeit.
The docs also mentions that this is not possible:

Then IPython runs its own transformations to handle its special syntax, like %magics and !system commands. This part does not expose extension points.

Does that mean that this run_all_cell_with_magics function can only be implemented in IPython itself?
