htaccess code to set QSA for all redirects automatically (globally)

Question

Firstly, this is the current setup, so that you understand where I am at the moment...

If I go this url:

http://website.com/login/

The server redirects to this script:

http://website.com/page.php?section=login

I have the follow htaccess redirect set up to do this:

RewriteRule ^([a-zA-Z0-9_]*)/$ page.php?section=$1 [QSA]

That my current setup and it works as expected. However, I want to be able to add string variables from the url onto the end of the redirect if they are present.

e.g.

http://website.com/login/?redirect=abc

should go to:

http://website.com/page.php?section=login&redirect-abc

At the moment this is achieved by using the [QSA] flag at the end of the redirect.

My question is, is there a way to achieve this same outcome (as using 'QSA') with a global setting at the top of the htaccess file? i.e. a setting that can be applied like 'Options +FollowSymLinks'?

I ask, as I feel like I have used something similar in the past, but can not find any trace of it.

Thanks, as always, for any help or suggestions. Looking forward to hearing them.
