option 1:
it would be really useful to be able to group the application custom properties by node to be able to edit all applications applied to a given node.
if you try to add the node in to the list of properties to edit, you get error:
ex. Our env. is such that we apply templates etc, and when ready to validate for a week or so with system we are replacing, we move to realm (custom property) of "staging", then to "production" when done validating.
This would allow me to edit all templates applied to a node or nodes at once. There are actually several CPs to edit like Alert Emails, stakeholder emails, etc...
Option 2
you also currently cannot do this (multi-edit) when managing application monitors grouped by host. As soon as you highlight more than one template, the edit button greys out.
