I totally understand the difficulty, you would have to trim the marked area between two markers, then “change” all the post sampled data to reflect the removal of middle data. I’m guessing that you would have to modify the sample numbers after the delete. For me, this is useful to trim captured data to help in the development of the Low Level Analyzer, remove data that is redundant, and focus on exercising each unique piece of logic. Saving huge amounts of time running through already debugged data. Can you export the data, trim, reorder sample numbers and re-import? That would be a short term solution.
