LC has groups, which can contain any number of objects, and when nested 
can even work like having multiple cards within them.  They can be 
shared across any card within a stack, but not across stacks*.

Nice for some things, but if you want a true stack object within another 
stack you may have to wait a while: this enhancement request is now 14 
years old, for what Gain Momentum introduced to the xTalk world as 
"Viewers"; while the LC team has shown interest in it, other priorities 
have displaced its implementation:

So for the foreseeable future, we have groups, sharable within a stack, 
and clonable anywhere, even into other stacks.  Using that as a 
foundation, we may be able to write a handler or two to give you a very 
Viewer-like experience, if you can share more about the particulars of 
how you'll be using them.



* Many years ago I experimented to find that you could display a group 
in another stack, but that was never intended and crashed hard as soon 
as you interacted with it.  Turns out showing groups across stacks was 
technically a bug, long since fixed. #HistoricalTrivia
