auth token generation in IntelliJ http client

We have a custom intranet endpoint to generate auth token for all of our services. So to use http client we always have to write two api one to generate token and using that token to call second api for actual functionality.

is there a way I can call token api in pre request script to avoid duplicating the token call all the time. 

we cannot store token in variable as userid or scope will be different for each api
