How to supply macro-id for dynamicContentMacros in the cloud

Hello Community,

Actually I was trying to set unique macro-id for the dynamicContentMacro rather generated by confluence.
Usecase is, For the plain-text macro In the cloud, the macro id is changing for every new edit so could not able get the precise body of the macro. If I can set to static macro-id then maybe I can get it. But not sure. Any thoughts.

Thanks in advance
