Best practice for workflow editing in Template Projects

Hi, I find the process of developing workflow scripts in a Template project to be laborous. Everytime I want to test a change I need to:

1. Save the script
2. Cross-project customization Verify and then Apply
3. Exit Template Project customisation 
4. Switch to my target test project
5. Perform the test
6. Switch back to template project
7. Enter customization and open the script again  

That's very tedious. Probably there's a better way, I'd love to hear about it. thanks in advance.
