Took a while to understand your question... The solution is easy:
1. Add empty string in pre-sentence array
2. Generate your random value for both pre- and post symbol and store it into a var
3. Use the var to access the symbols in the both arrays at the same position

Yeah, a bit dirty. Btw. the sentence which confused me so much that I understood your question was: "¡La ducha es demasiado grande?". Undirty.
