Can I influence how ConEmu identifies line numbers when using hyperlinks to launch an external editor?

I’ve able to configure ConEmu to open a file in an external editor when I click on a file name hyperlink in the console. Typical use is clicking on a path in a Python error stack trace. I’d like it to not only open the file but also jump to the line number on which the error occurred.

Looking at the guidance in ConEmu’s settings it states that I can use a few macros when setting the command used to launch the external editor, e.g. %1 should substitute for line number, %2 for column number etc. What doesn’t seem to be configurable is how ConEmu parses the line/column number and provides it to these macros. Is this something the user has any influence over?
