I conduct my analysis across a monthly and weekly chart side by side and some of the layers are relevant to both timeframes meaning I need to maintain 2 sets of the same analysis.
It would be super awesome to have the ability to identify a layer as being relevant to all charts on the same page that are for the same stock.
Do you use Layouts? I can not see us building what you are asking for but between layouts and the export/import of layers, you should be able to get very close.
