Internal Tickets between Staff

Hello.

This might not be the usual use case, but, we are using Support to help us also keep track of things we need to do or collaborate on.

The internal mail system is not what we want to use in this case, since we want the full features of the ticket system.

Is there a way to natively use Support in this manner to cut out some of these steps.

For example, now we have
Created an Internal Department
Create new visitor accounts for each of us (using the same email we use as staff)
create a ticket with the staff visitor account
turn off Email notifications
assign staff to both of us
Save
Use in the same way as an external ticket.

I am thinking the step I am concerned about is creating a visitor with the same email account as our staff accounts.

Suggestions?
Thank you  - Paul
