How to make BASH/ZSH replace relative paths with absolute ones?

Question

linux

The situation is as follows: I work with a symlink to a directory, there is a certain file above the level of this symlink. Trying to call "mv" and move the file to the current directory:
symbolic_link_to_dir $ mv ../somefile .
But I get an error that the file ../somefile doesn't exist even though auto-complete worked. For a beginner, such behavior can generally lead to a stupor and a deep misunderstanding of the ongoing processes. And in fact "mv" reads the real inode of the directory and goes higher in level of it, and not the symbolic link.
The question is: how can I make it so that there is a rise in level relative to the symbolic link, that is, the current directory. So that in fact something like this happens: UPD: if this is possible at all, for example, on ZSH , I ask you to go to the studio.
symbolic_link_to_dir $ mv `pwd -L`/../somfile .
