Hi @Sakshi Jain ,
Welcome to the Atlassian Community!
Cloning action is supposed to make exact copy of data presented on issue. You can always edit this issue later.
If you know you will need to copy certain issue, you can make a template from it with only required data, then fill it on the copy created from that template.
There are 3rd party apps which can help in making templates or modification of issues.
I'm from the team behind Excel 365 Connector for Jira app, in which you can easily modify or create new issues and ... use Excel features to populate data: https://marketplace.atlassian.com/apps/1222961/excel-365-connector-for-jira?hosting=datacenter&tab=overview
