Createing multiple files from one template

[arep]

Hi, this is not an issue, but a question.

In consul I have a structure like:

customers/
  id1/
      key1
      key2
  id2/
      key1
      key2

...
I have created a template that uses File.write to write files id1.json, id2.json and so on, with the key1, key2... inside.
Are there any problems with this approach? Or another better solution?
I don't know the id1 and id2 in advance, so I cannot use just a separate template for each id.
