Understanding Relume and Webflow Integration: Update Concerns Explained

Hi there, I am just getting started w/ relume and i love it so far! I am using Webflow after the relume process. Quick (maybe dumb) question. But lets say I am done in relume and I export to Webflow. Then I do a bunch of design in webflow - adding photos and logos. But I decide I want to go back and make some changes in relume (to pages I have already imported and designed). When I re-export, will it overwrite the changes I have made in webflow - or will it just update the new copy / components. In other words do I have to be completely DONE DONE in relume before I start webflow. And if I can't go back - is there a way to access relume's features in webfow (like adding a component, or writing new copy?)
