Why are attached charts to notes being updated with new drawings/updates? I thought the purpose of the attached chart was to have a snapshot of what the chart looked like at that point in time?

I.E. - I drew one trend line on 8/27/16 and attached the chart to a note I created on that day. I then draw a new trend line on the current chart of the same symbol on 8/31/16. When I pull up the note on 8/27/16 and look at the attached chart it shows both trend lines!

It looks like the attached charts will keep any markups that are deleted from the current chart, but it also adds new markups made to the current chart and this gets confusing.

Any way to fix this?

Thanks.

Thank you for your suggestion.
