Using DB module in testing with transactions

I want use this codeception module on project where we run test cases inside database transactions.
I already did some hacks on my project to achieve that; and also i make PR proposal https://github.com/Codeception/module-db/pull/60 but i did not get any feedback;

Please, can you give me some tips how i can achieve that with this module if that is posible?

If this is not possible jet, please let me know what do you think about my proposal, and do you see this as valuable functionality; My idea is share my project/test connection instance with module, so module can assert changes made inside db transactions;

Thanks
