It is possible to add or remove a unit or building, but this must be done directly through Smovin.
As a Smovin client, you benefit from the maintenance management service provided by Urbest, but the configuration of your workspace is linked to your Smovin subscription.
The Smovin team has set up your workspace, synchronized all your information, and connected both services. As a result, any changes made in your Smovin account (such as adding or removing units) will automatically be reflected in Urbest.
