Hi Sanjeevkumar thank you for posting in the Lucid community! Our sincere apologies for the delayed response on this thread--I wanted to follow up in case this answer may still be useful to you and to provide a solution for other users who see this thread in the future. 

There is not a way to automate this but you can manually add a swimlane or another container shape to border your grouped shapes.

We’re very interested in your feedback and committed to continually improving our products. If you’re willing to share, we’d love to hear more details about your use case or what you’d like to see in this experience within this thread. I’ve also converted this post to an idea so that it’s visible to others within the Product Feedback section of the community - from here, they can upvote it and add details of their own.

Finally, for more information on how Lucid manages feedback via this community, take a look at this post.
