Hi Liou

Thanks for posting in the Community!

Unfortunately what you are trying to do is not currently supported in Lucidchart. However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form?

As a growing company we take our feature requests very seriously as we are continuously looking for how we can make our product more useful and effective for our users and we pass that information directly to our product development team.

For the record there is a DevOps shape library available to users on Individual Team and Enterprise accounts which contains a few DevOps shapes. To access your shape libraries please follow the steps detailed here: Import and search for shapes

Let me know if you have any questions!
