Nginx RTMP dynamic stream name - php

Question

I'm trying to create a simple RTMP/HLS server to be able to stream to and to view streams from, however, I am unable to change the name of the directory to which nginx-rtmp-module (module) saves the data.
Everything works just fine, I am able to stream to server and then view the HLS stream in browser, however, the only way to do so is to enter the Stream Key as the target folder on the server to get the m3u8 file.
Currently I have the following settings:
Stream key is generated on the server and then shown to the client
Client enters: rtmp://live.local/live as the endpoint and then inserts the key generated in step 1
Upon the request to start the stream, module calls on_publish to http://app.local/stream/start where at first, it checks if the key exists in the database, and if it is, it then creates new database entry for stream (with UUID as the primary key), receives the key obtained through entry creation and returns it to the script
Script takes the UUID obtained in step 3, then it uses SHA-512 algorithm to generate unique string (which was planned to be used as the directory name)
After hashing is performed, script returns 301 with location header
The stream itself is now renamed, however the folder in which files are stored is still the Stream Key instead of hashed value obtained in step 4 and returned in step 5.
Does anybody know on how to:
Rename stream (I guess I've done that already)
Rename directory for the stream files
OR is there a way to dynamically rewrite all requests, for example, client requests http://live.local/stream/here_is_the_hashed_uuid/index.m3u8, php takes the hash value, gets the list of active streams, hashes every streams' uuid and if matched, returns files from the other directory
PS: Just a small example of what I have now and what I want to achieve
Stream key: test_stream_key_user_1
Hashed key: 73E179A6DB3796A3120319BFE80763427A2122253A5C1D347461268304B28CEB98CE3813DDF5FA8B7173937ED9386169FD3BF8E8C3765BC53BB151C7F5B1431E
Current directory naming: /tmp/hls/test_stream_key_user_1/index.m3u8
Desired directory naming: /tmp/hls/73E179A6DB3796A3120319BFE80763427A2122253A5C1D347461268304B28CEB98CE3813DDF5FA8B7173937ED9386169FD3BF8E8C3765BC53BB151C7F5B1431E/index.m3u8
PPS: I thought that my nginx config files might help.
