CodeBuild Show Better Description in Source Version

We have a CodeBuild project that is set up to build the develop branch from our GitGub repository when changes are pushed to it. In our case we used a 'Push' event trigger with this in the head ref ^refs/heads/develop$ That works but when you go to look at the builds to see which one you want to deploy, it just shows the merge commit hash for the develop branch under the 'Source Version' column rather than saying "develop". If I do a manual build and use 'develop' as the source it does say 'develop' in the source version. Is there a way to control this so that the Source Version shows something more meaningful?

thanks
