Prompt values before request

First of all: Hi! :slight_smile:

It looks like I cannot find the right search terms, because my searches have been unsuccessful so far.

Is there a way to display something like a form before sending a request to define values for local variables that are necessary for this request?

I tried the JavaScript function prompt(), but it was not recognized by Postman. Alternatively, I would set the variables in the pre-request script and let the users adjust them there, but this causes the request to change and the user will get a prompt to save it.

Hopefully I could describe my need in a more or less understandable way. Any hints for a solution are welcome. :slight_smile:
