edit TOML file in place

[Araxeus]

Lets say i have a very long and complicated TOML file, which contains a line:

[myPackages.coolPackage]
version = '0.16.1'

and all I want to do is change the version to 0.16.2, is there any way to edit this specific line without rewriting the whole file? (and by doing that, ruining the formatting of all the other lines, comments, etc)

I expect the answer to be 'no' but maybe you have an idea how could we do that? (which is not manually editing the text via a regex)
