Hello,

I was using Level0 as it do help me to group changes based on the visual map. However, it could not handle relations and ways properly and stuck on loading their child ways/nodes.

I saw "The JOSM editor permits splitting changes done across a larger area in saves of smaller parts" on the page. However, I only found this: https://josm.openstreetmap.de/ticket/19712 .

Is there any functionality/feature to split edits into changesets based on country/region/province/state in JOSM? Is there any link describing it?

Thanks for the help.
