Yes. While your main profile will only list you under one primary job title, if you have worked as a BTL crew member in more than one job capacity, you have the ability to add that job title when you upload your credits.
Ex: You can list that you’ve worked as a costume cutter, costume assistant and costume designer on various projects. However, you will need to choose one category as your primary job title.
The job title you want hiring managers to see should be listed first.
