Please make prompt subject keyframeable for animation

[TutajITeraz]

Is your feature request related to a problem? Please describe. I would like to create animation, changing prompt in the middle of it.

Describe the solution you'd like Add a standard key-frame pressing I over the Subject field in Render Tab.

Describe alternatives you've considered It can be also made as in "AI Render" plugin - as a text file with prompts writen line by line [frame_number]: [prompt]
