Duplication of intents and entities while importing an updated version of a pre-existing flow of same agent using client library

**ISSUE**: Currently with the latest release of dialogflow-cx in console if we import a new version of pre-existing flow it asks us whether to replace the original intents and entities or keep the originals ones or create new copies of the resources, but this functionality is not available in the client library .

**Is your feature request related to a problem? Please describe.**
My specific problem is I want to automate the import flow process; if a change is made in a flow of dev bot , the new version of the same flow should be imported in the prod bot ,
but on doing so from client library all the resources and the flow itself is duplicating

**Describe the solution you'd like**
I am looking for is; if certain conditions or parameters are added to the request body of payload which can prevent flow duplication

**Additional context**
All I want is to be able to do this from client sdk

Please , quick responses and any suggestions can help me , I am in a bit of urgency
please help
