Using the AI PR descriptions and the 'Summarize changes' features needs to be extended to include the use of PR templates pulled from VCS.

Currently, you can only use the 'Summarize changes' without using a custom PR template. The AI output is helpful but using any of the suggested content has to be copy and pasted into your PR template. Instead, it would be more useful if the suggested content (##What has changed?specifically) can be injected into the use of an existing PR template.
