Customizing Look and Feel of registration email

[Jens Kisters __SeibertSolutions]

Hello,

i see in JSD 3.16 there is a way to customize the HTML mails.

I tried this and managed to customize the emails. 

But it doesnt seem to apply to the email that is sent out when a user is added to a company.

I mean the email that contains the link where the user can set his name and password.

Is that possible with 3.16? Or can that be made possible with an upgrade

Thanks in advance

Jens
