Can I edit the original css stylesheet of the theme I am using and then re-upload it back instead of using css editor in the builder?

Is there a way to download the css stylesheets of the theme from the order form so I can actually edit it instead of overwriting styles in the custom css fields in the editor and then re upload it back so there is one stylesheet with the css styles? There are just so many overwrites of the same elements from different stylesheets when I edit the css on the builder and not directly. I know that I can download the source code but can I re-upload it back so that I actually edit the original stylesheet instead of overwriting it with !important through the css editor?

You may  get the CSS sheet by downloading the forms source code.

However, once you have edited the forms source, you would need to upload it to your server  or embed it to your webpage for the form to work.

Hope this information helps.
