If you have a subpatch with polyphony and save voice 1 preset direct to file, then try to load voice 1 preset into
voice 2, it fails since the item IDs in square backets above patch elements do not match.
The preset file contains data like this:

[VERSION]
save version=115
usine version=HH5
date usine=211124

[6977464658333720400]
CHUNK=504730310000000074

My suggestion is for specific Polyphony support to allow this.
For each element that is duplicated in all poly voices (so it can safely reload using data from another voice),
the ID should be included from each voice, e.g.

[6977464658333720400, 7977464658333720411, 8888464658333728888]
CHUNK=504730310000000074

The most important such item for me would be the plugin itself.
It would be reasonable to only allow this for items directly in the subpatch, not for items in a sub-subpatch,
since it could then get rather complicated.

For a fast loading of presets, we choose a very light storage system based on presets-ID. It's not easy to change it now, but we'll think about.
