Synchronizing annotation regions across ECG and IMU time-series signals in Label Studio tasks

Hi,

I am using Label Studio to annotate ECG and IMU data together.

I would like to create a region (for example, “sitting”) on one signal, and have the exact same region automatically appear on the other signal within the same task. In other words, if I label a time interval as “sitting” on the ECG timeline, I want that label to be on the IMU timeline for the same time range.

How can I do this?
