Question: can I change my fzf query with a shortcut

[ayroblu]

• I have fzf 0.30.0 or above
• I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• I have read through the manual page of fzf (man fzf)
• I have searched through the existing issues

Hey! I was wondering if there's a good way to adjust the query on the fly?
My use case is that I'm running Rg on a specific directory, but sometimes I'm a little too deep and need to go up a level or two, it would be great to hit some hotkey and then it searches one directory above. Not sure how I'd do that with fzf.vim

RG kinda has a similar idea, but instead of relaunching the search on every keystroke, I only want to do the search once, but then if I need to I want to jump up a directory
