Can you add the ability to save custom fields and priority to project templates please!!

I have a task list for each of my custom website projects that has 60 tasks. I've added custom fields for these tasks to help me organize them by project stage and I've set priority for each task. I then used this project to create a project template but none of my custom fields or priorities have saved to the template. Now every time I want to use this template, I have to add these custom fields and priorities manually to each new project. Would love to have these data save into the template so I can reuse this template easily and quickly for future projects!
