Hello. Thank you for contacting the Toolset support.
Currently, there is no feature to link the container block but this is one of the popular request we are having and we do have internal ticket for it and fortunately our Devs already added this feature and this feature is under testing.
I suggest you to wait a little more and its most probably added to next release of Toolset Blocks.
I'll keep you posted once we officially release this feature.
