If its one per city and you really do not feel that making over is an option, you are stuck with increasing the number of people who can accept build requests in order to expedite the acceptance process. There aren't many other options here.
The city manager can see the city in the personal inventory, can click on the planet square and view the city from there, can have access to the planet's stats where the city is located.
These are tasks related to a Manager. Building is done by minions ;-) and they must make efforts.
The problem is that the city slab is owned by one party, and the type of building is "owned" by a different party. To avoid hostile take overs, there are no privs that you can give to bypass the build permission step.
