Describe the bug

In sequential pipeline, there is no option to insert an environment in between 2 existing environments

To Reproduce

1. Create a CI
2. Deploy to dev
3. Deploy to prod
4. Try to add stage env in between dev and prod in the same sequential pipeline

Expected behavior

It should ask me whether I need to add this env in between or in parallel to the env

Current behavior

It automatically adds the env in parallel using the + button in front of the existing env
