I already tried to do it with a per particle expression but I encountered a problem. I was thinking of duplicating the geometry in a creation expression, storing the duplicate's name in a per particle custom attribute and then deleting the duplicate when the particle dies. Then it would have been just a matter of moving the geometry in a runtime expression.

The problem is that you can only (?) have per particle custom attributes of float type meaning I can't store the name

Any ideas?

*edit*
Maybe I could rename every duplicate to something that includes the particle's Id in it's name but it wouldn't be fool proof...
