Callout feature

Request to implement Callout feature, Its a feature that can pinpoint the exact location of price action and also write comment at the pinpointed location. Its a very important feature as there are many points in the chart that i want to comment during my back testing. However there is only text feature available which couldn’t be used to pin point exact location of price movement. Since screenshots are usually used during journaling, having callout feature saves us a lot time and make everything way more efficient.
