Manual "data collect" specific objects

I'm orchestrating the hole infrastructure:

1. AD to create users and groups for entitlements
2. vCenter to create Resource Pools
3. NSX to create networks
4. vRealize Automation to create:

• machine prefix
• Business group
• Reservation

But when I try to create the Reservation, the Resource Pool and networks are not in vRealize Automation inventory. I can't start a data collection every time I do this process so I would like to add this objects manually (like a DEM worker).

Is this possible? Can I force the collection of specific objects into vRealize Inventory on demand?

Thanks a lot,

D.
