The naming convention can solve part of this issue.
the column of the environment variable name is a bit short which while opening you would see a lot of them starting with same 'name'.
In addition to the grouping solution, I do like to recommend that the value of environment variables should be fully shown which give a lot of easier view for our control.
Currently, we have 8-9 processes using around 60 environment variables. Sometimes, it's a bit of pain.
