Is there a workbook type function available in MC?

I currently have 5 workspaces dedicated to my intraday trading.

I would also like to create some workspaces dedicated to swing trading, but I do not want these tabs to be in the same tab/workspace area as my intraday tabs.

Is there a way to create a workbook type thing where I can tell MC to open my intraday trading workspaces/tabs or my swing workspaces/tabs? If not, that would be an incredibly handy function. Basically the hierarchy would look like:

WORKBOOK = holds your workspaces
WORKSPACES = holds your tabs
