I'm afraid its not so straighforward in Kyma to re-order or re-arrange Presets. We are hoping SSC will improve this user experience soon, as anyone who works a lot designing sounds soon creates hundreds. The list does need to be managed/sequenced, especially if you want to perform with them.
For now, the best way I use is numbering and trailing character.
So for example, "01 intro"
then you make a tweak which feels like it should be next in the list
"01 intro++" and so on.
if you want to insert something between "01 intro+" and "01 intro++" you can use a lower ASCII character, something like "01 intro +*"
