Hello @mark.aronin,
A callback that could be helpful is incrementalSelectionBatchBegin (and complimentary callbacks incrementalSelectionBatchEnd and incrementalSelectionEnd). As stated in our docs, incrementalSelectionBatchBegin is
Triggered BEFORE a batch of incrementally selected entities is put into the
SelectionManager
I also wanted to briefly mention the function setSelectionFilter. While this function does not pre-empt a selection operation, it can be handy if you want to quickly manipulate certain nodes. An example is provided in this forum post.
