Dispatcher app
In the Dispatcher app in the Transfers tab there is the option that says Marketplace. This feature allows you to find transfer requests available to your company and all other partners, which you can claim and assign to your drivers.
About Marketplace transfer requests:
They do not expire.
They can be claimed by anyone.
Once you assign them they will be available in the Upcoming transfers list.
