How to achieve Incremental deployment of Sitefinity Code Fil

Hi
We are new to Windows azure and are developing a Sitefinity web application. In the beginning of the project , we have deployed complete code using Sitefinity Thunder to different environments which actually publish complete code. But now as we are in the middle of development , we are just required to upload any new files created which can be quite less in numbers (1 or 2 or maybe few). Now if we deploy with thunder , it publishes all files and then deploys complete code which takes good amount of time. Is there a way we can deploy only changed or new code files via sitefinity thunder or is there any other way with which we can only upload only the changed files?
Please help.
