Hey @Victor1890, thank you for your contribution!

I'll take the time to review your PR as soon as I can, I'm under a bit of pressure right now.

hey @Victor1890 I looked over the changes and I'm curious about the motivation for this change. it does factor out some code to a function, but that code is only used in one place and with the changes only five lines are reduced in the original context (four if you include the import that is required)

I couldn't take the time to format a comprehensive response but I can complement your comment (which I agree with), the initial motivation for this was to refactor this huge block I (shamelessly) added to the codebase.

This is all discussed in #704 (comment), but I think this PR kinda misses the target, although I appreciate the effort and it's going in the right direction.

I tried giving it a look and started a review yesterday but realized the real implications got out of my head and would require a few hours of playing around, which I can't afford right now.

I hope the quick context intervention can help!
