Is your feature request related to a problem?

We are working on a project where the requests are heavy jsons (50kb aprox). Our postman collection have several folders and cases, so our collection project file is about 15Mb. This file is stored and shared with coworkers via git and is dificult to do merges and diffs with this file size. We also use variable substitution on requests (with mustache syntax {{}}).

To mitigate this problem we had tried to load our request from external files and make the collection file lighter.

We try to save the request as external file and use body -> binary and load the external file. When we launch the request the present mustache variables in the file are not substituted.

Describe the solution you'd like

Postman substitutes mustache variables on binary files when the files are json. Or maybe a checkbox or feature flag to enable variable substitution...

Describe alternatives you've considered

Load local external file via pre-request but i think is not posible due to security reasons....
