Query: Conditional prompts in cookiecutter.json

[vithalsm]

I have following requirement while writing a project template.

cookiecutter.json:
"project_name" : "test-proj"
"ptype": ["a", "b", "c"]

Now, based on ptype values entered, further sub options to be prompted.
For e.g.
if ptype==a"
Request for another option related to 'a'
else
Some other options

Wondering if its possible to implement something like this.
