It will be better if we can create different workflows and Jira admin can select the workflow for each projects from the list of created workflows.

Example for workflow groups:-
Workflow 1:- The workflow Includes statuses such as "To Do , In progress and Done"
Workflow 2:-The workflow Includes statuses such as "To Do , In progress , In review and Done"

Also it will be better if we have the same feature for setting the Jira status. Means , we can create different groups of status lists and we can select the needed group in each project. Or we can set one group of status for all projects.

Example for status groups.:-
Status group 1:- Includes "To Do , In progress and Done"
Status group 2:- Includes "To Do , In progress , In review and Done"

In both status and workflow , either we can set for all projects or for selected projects.
The above are needed for team-managed (formerly next-gen) projects.
