I have multiple codes for Spark and I'm not sure yet if I want to add them to a single account (ie multiple employees in one account) or keep them as individual accounts.

1) Is it possible to switch back and forth between the two scenarios in the future?

2) And also if they are merged to a single account is it possible to restrict users to sub accounts?

3) Also is it possible to change the email addresses used in the future?

4) When merged would the bank statements credits also be merged (ie the same way it would happen if i put the codes into a single account right now)

Thanks a lot for the great product!
