Parfor loop with complex structure

My idea is to run multiple independent simulations only changing parameters, but I want to keep all the results stored in 1 unique workspace that is also loaded so when I stop and rerun the code it checks from which iteration it should continue.
For this purpose I have 3 nested loops, the inner one being a parfor loop and the outer ones a for loop. The problem is that for all this data to be organized I want to dynamically create sublevels on the workspace structure named after the iteration indexes and I want to store 12 different variables with such different dimensions and types.
I tried to index the first level of the output structure as in examples, also creating an empty structure inside the loop but it does not work. Also, it seems save() cannot be executed inside a parfor loop.
Is there some workaround or method to accomplish my idea?
