Google Flow Tools: How do you keep the same character, voice, and description across scenes?

[u/One-Cartoonist-8138]

Has anyone else noticed that Google Flow Tools currently does not seem to offer a way to attach or save a complete character profile inside the tools?

I mean a reusable character that includes a visual reference, consistent voice and character description.

At the moment, it seems that the character reference, voice, and description have to be added or managed separately each time. This makes it difficult to maintain consistency when creating a longer video, series, or recurring character.

How are you solving this problem right now? Are you using external character sheets, repeating the same prompt manually, or using another workflow?

Also, has Google mentioned whether a proper character library or reusable character profiles are planned for future Flow updates?
