Geo location

We have couple issues with jobber, maybe just not using correctly.

we have 20 users aprox. each user makes there own estimates and Invoices from Jobber from where they log in etc..., why is that they have to select their names on the invoices and estimates, How to make it so is automatically.

Also I understand the software is cable of using Geo location, if they are at a address or client per happens, Why is that all customers come up for address, would be ideal for the location that the job is being done, for that location come up as a first option for customer name?

Does any one knows?

Thanks for all the Help
