Is there no rule/function inside SC that forces an upload or split an upload based on time stamps the items were put into the upload buffer? This is an on-site survey tool but used too often to map another place 'from memory' in a far away location and then step past the 'this is far away, are you sure?'
At any rate, a SC mechanism to split uploads by time segments would be great as I can see not everyone has a Euro/world coverage in the data plan and wifi is needed to do an upload (Nicosia airport/hotel maybe?)
It starts with awareness though, hit the forced upload button before moving on, at least that's what I do cycling the countryside and seeing this or that along the way.
