Welcome to the Asana Community Forum @spiritfxlexi!
Here is an existing feedback request thread and some workarounds mentioned: Create Multiple Asana Projects from One Template At Once
Also here is another feedback request thread you might be interested in with an option via Flowsana to create new projects from a template via rules so you could automate the process.
Oh actually this should solve your problem, see the tool IDO launched just a few days ago: Bulk create projects based on a template
I hope that helps
