Possible to merge clients?

[sunrisepro]

I have a client who has two Blesta accounts, which I did not notice until now. My guess is that I had invoiced him initially for a website and then he purchased hosting later without logging in first. Both accounts use the same email address, which I thought would not have been allowed. Is there any way to merge them?

transfer the services and deactivate the account. blesta has a setting to not allow multiple accounts with the same email, enable that
