(Feature Suggestion) Mirror modifier for Node Placement / Movement etc.

[CrezzaC]

Hello!
I want to drop a nice suggestion for the Affinity Designer v2 app.
I've had times when I wanted to make an icon graphic that is intended to be symmetrical in design, yet I have to manually cut the shape in half, duplicate the side I want to match with and stitch them together. Wouldn't there be an easier way to place nodes down from a line of symmetry and have the changes show up on the other side? Would this be possible? Could an idea like this be taken further or is there some technique I'm missing perhaps? Genuinely curious if this would be something nice to add to the app as a quality-of-life thing. Having the ability to add/move/modify and delete the nodes of a curve on a symmetrical line or mirrored line?

I'd love to hear some thoughts if possible. :)
