How can I add a custom meta description and title for each question page in Q2A for better SEO?

Question

I’m learning SEO and exploring how Question2Answer handles on-page optimisation. By default, each question page seems to use the question title as the page title, and the meta description is created automatically from the question text.

I’d like to know:

1. Is there a built-in setting in the Admin panel to customise the meta title and meta description for each question?
2. If not, is there a recommended plugin for SEO meta tags in Q2A?
3. Does Q2A support canonical URLs and an XML sitemap for Google Search Console?

I’m using the latest Q2A version. Any guidance or plugin suggestions would be appreciated. Thank you!
