hi and welcome!
there's nothing ready to use,
but an option for you is to change the folders using script commands.
so you can prepare your script, and decide to run it inside Menu > Debug > Run script
or a different solution.
Your script may even take some inputs somewhere, as parameters of the work is going to do.
Manually it means that you right click and "edit resource" for each folder.
I expect this to be a 20 seconds operation, x30 means 10 minutes.
It's up to you.
There's no option in HFS 2 to have the vfs in plain text, sorry.
HFS 3 (still in alpha, but usable) only uses plain text for all configuration, and doesn't require restart if you edit it while running.
