Toggling between creative modes

We should be able to go from text to image into the generative, fill and back out into the text to image again and continue to do this to keep on refining. If this is already a feature, it's not clear on how to use this to go back to continue working with the other filters. It seems like a one-way street.. if somebody has direction on how to accomplish this please inform me I am really enjoying using this and I feel it just needs to be tweaked a little bit more to get things more user-friendly I'm sure the trillion dollar corporation can afford such workers to get this done.
