Notification into one form

Notification into one form

Hello,

I'm building an application and have a question about it.
I would like to script the following:

Step 1:
1. An user can make a mention in Zoho Creator for his vehicle like: Mirror is broken.
2. An other user can make another mention in Zoho creator for the same vehicle like: headlight doesn't work.

Step 2:
The manager can check out these mentions and fill in another form for a supplier to fix it.

Step 3:
The manager fills in a form and selects the licenseplate of the vehicle and the supplier. Now both mentions of the users should be imported into a sub-form so the manager can send a notification to the supplier.

Question:
Is it possible to import records from another database, based on a lookup-field (license plate) into a subform of another form?

This would seriously help me. Can anyone has any ideas?

Hope to hear from you soon!
