Is there a better way to use rollbar error reporting with flask?

I just came across rollbar and wanted to include it in my Python project.

This is the standard way in which I am told to implement rollbar from the website.

import rollbar

rollbar.init('KEY')
try:
    a = s
except:
    rollbar.report_exc_info()

Is there a better way to implement this without going through all my try except blocks and replacing them with rollbar.report_exc_info()

Can there be a decorator implementation for this? My current project is a Flask app that provides API's to end users.

Here's an example for rollbar integration in Flask apps.

https://github.com/rollbar/rollbar-flask-example/blob/master/hello.py

@app.before_first_request
def init_rollbar():
    """init rollbar module"""
    rollbar.init(
        # access token for the demo app: https://rollbar.com/demo
        'fc316ac1f7404dc28af26d5baed1416c',
        # environment name
        'flasktest',
        # server root directory, makes tracebacks prettier
        root=os.path.dirname(os.path.realpath(__file__)),
        # flask already sets up logging
        allow_logging_basic_config=False)

    # send exceptions from `app` to rollbar, using flask's signal system.
    got_request_exception.connect(rollbar.contrib.flask.report_exception, app)
