Reipload Grasshopper files / versioning

Is there currently a way in which grasshopper script can be updated
For example a file is uploaded: table_ver1
I make some changes in the script and I want to update to tablever2 and so on without setting up and uploading a new file everytime.

At the moment, the recommended workflow for updating models is to use the “Import Settings” feature, which lets you apply all parameter and viewer settings of a previous model to your new uploads. That ways, you can re-use the setup you manually worked on previously. It is however still necessary to upload a new file, which will be improved in the future.
