Is there any simple way (standard component, python or C#) of combining 2 data-trees into a single one, with all lists remaining unchanged but having the branches renumbered.
I tried using Entwine but that would give me a deeper tree (with new indices at the first position) which I don’t want.
I don’t want to use any plugins.
I want it to look like the bottom and not like the top.
If you uncheck “Flatten Inputs” option ofEntwine, you’ll probably get what you want.
And you could also use Stack Trees fr Treesloth plugin.
Something like Stack Trees is what I was looking for. But is there a way to do it without installing any plugin? 
I need the tree to have the paths {0;0}, {0;1}, {0;2}, {0;3} etc.
Actually entwine set to graft and pathmapper to renumber the paths solved this! Thank you @HS_Kim!
