Additional control option for SEO recommendations scan

Hi all- thank you for submitting this idea. My team is interested in learning more about why you would like to either stop a SEO scan in progress or limit a scan to specific subdomain.
Is the main reason you would like one of those options to reduce the amount of time that it takes the scan to complete? Or is it moreso to reduce clutter in the SEO tool? (Or both, or other?) What kinds of subdomains would you exclude from the scan and why (I know knowledge bases were given as one example)?
