New application creation - Blueprint

We are trying to create a new application like incident mgmt, as per the Blueprint available none of the blueprint provided workflows and data types are inline with what is needed for our new application.
We see some issue relate to deleting the existing workflows as part of Blueprint journey which is tedious and takes lots of time for deleting, there is no central option where we select unwanted workflows, personas, data types and delete instead of each deletion.

For bulk changes, I would recommend Blueprint AI Assistant its really very good and merging case types or removing lots of items at once.

Yes, AI Assistant was able to delete most of them, but certain processing was not able to remove by AI assistant.
I tried with a Incident management application with industry as Other

If you try again through AI assistant, it might remove on 2nd time.

I tried multiple times, but gives an error message cannot delete the workflow.
