In Multiply, you can save your own templates by adding text blocks. The way the prompt saves depends on whether you edit it in 'Edit Template' or directly in the template instance.
Edit Prompt in Template Settings
If you click the three stacked dots on the left and choose "Edit Template", you will enter the template settings. Any changes you make to a prompt here will apply to every time you use this template.
Edit Prompt in Template Instance
If you need to make a one-time change, edit the prompt just in that template instance.
When to Edit In Which One?
If you often write poems about cats, edit the prompt in the template settings. This way, your cat poem settings are saved and used every time.
If you suddenly want to write a poem about a dog just once, change the prompt in the specific template instance.
As shown in the videos, when you press "+ New", the system uses the prompt saved in the template instances. The prompt for the dog poem only saves in that particular instance, so it won't affect your usual cat poems.
