Connect Smartsheet more than once with the same login

A Smartsheet connection carries one sheet, so a second project needs a second connection. Adding one used to fail on the way back from the Smartsheet sign-in with "A resource with these values already exists", because Building Swell allowed a single connection per Smartsheet account. Anyone with one Smartsheet login hit that the moment they tried to map their second project.

You can now sign in with the same Smartsheet account as many times as you have sheets to map. Each connection keeps its own sheet, mappings, schedule and activity, and syncs on its own.

One sheet still belongs to one connection. Pick a sheet another connection is already syncing and the mapping will not save: two connections on one sheet overwrite each other's work every cycle. The sheet list says which connection has it, so you can see that before you choose.
