Change sequence settings

MakePerceive

I'd lie to be able to change the size of the current sequence. Eg I'm working at 3840x2160 (16x9) and I want to do different versions for social media, so I need 1x1 and 9x16. I'd like to trigger a shortcut that could:

duplicate sequence and change suffix (1x1)
open the newly duplicated sequenece
change resolution, read the existing xy dimensions and change based on that. eg if the sequence is 1920x1080 and i want 1x1, the sequence would change to 1080x1080.
Maybe it gives more flexibility to do the above steps as separate options that can be combined in a single command. Additionally the user might need options to set clips to frame.
Sometimes I work with footage that has been shot at 3840x2160 but is intended for 9x16, so it would be nice to be able to convert sequence to 2160x3840 and rotate the items *once agian user might want option to rotate left or right 90degrees)

You can do it now by mixing some keyboard shortcuts simulation.
Like open sequence settings, navigate with Tab to proper input field and changing numbers there.
That said, I do plan to give command that will allow change sequence settings without complicated macros.
