How to manually copy one object only to another chart

Does anyone know how to manually copy one object (eg vertical line including its name and other properties) from one chart to another please? Or a script?

We don't want to copy all the objects on one chart but even better would be 'all selected objects'.

Thanks in advance for any consideration and replies.

Did you ever figure this out?
I know you can make a template of a chart and copy that template to another chart/time frame. But that copies ALL the drawn objects. Still cant figure out how to get a single object to be copied from one charts to another.
