How to create a collection with my original template

[wakiyamap]

Hi. Thank you for always creating wonderful works at the foundation.
I use google translation, so I'm sorry if I use strange english.
I have a question.

I am creating an NFT that changes the return value of tokenURI every time at the request of a friend.

However, this does not allow it to be sold on the foundation.
So, I thought of modifying the template.
I tried it and it seems that I need to deploy Template and CollectionFactory and RoleManager.

Is it correct to do it this way?
Looking at the description of drop, it says that enable dynamically switching the tokenURI response based on some external event is also supported. I would like to know the correct way.

Thanks.
