A useful feature when using auto-discovery / auto-registration actions when adding hosts would be the following:

• Setting Host User Macros
• Setting Host Tags

Say for example (in our case) you have an environment where:

• There are multiple sites with multiple devices
• Each site has a proxy that monitors the local devices

You may wish to:

• Add some host tags (i.e. SITE=XXX)
• Add some user macros (i.e. {$SITE_SUBNET} = 'YYY.YYY.YYY.YYY')
